Description

The embodiments disclosed in this specification and drawings relate to medical monitoring devices and medical monitoring systems.

Conventionally, for medical equipment with moving parts such as radiation therapy equipment, a technique is known that predicts interference between the medical equipment and the patient by performing an interference simulation in advance. In such interference simulation, a virtual patient model is used to predict interference between the medical equipment and the patient.

However, the position and posture of an actual patient may differ from that of a patient model. As a result, medical personnel must monitor whether there is any interference between the medical equipment and the patient.

The medical monitoring device and medical monitoring system according to this embodiment will be described below with reference to the drawings. In the following embodiment, parts with the same reference numerals perform similar operations, and duplicated descriptions will be omitted as appropriate.

(First embodiment)
A medical monitoring system 1 according to the present embodiment will be described. FIG. 1 is a diagram showing an example of the configuration of the medical monitoring system 1 according to the first embodiment. The medical monitoring system 1 includes a radiotherapy device 10, a monitoring camera 20, and a medical monitoring device 30. The radiotherapy device 10, the monitoring camera 20, and the medical monitoring device 30 are communicably connected via a network. The configuration of the medical monitoring system 1 shown in FIG. 1 is an example, and may be other configurations. For example, the medical monitoring system 1 may include a plurality of the radiotherapy device 10, the monitoring camera 20, and the medical monitoring device 30, or may be connected to other devices or systems via a network.

The radiation therapy device 10 performs radiation therapy by irradiating the patient with radiation according to a predefined treatment plan. The radiation therapy device 10 also has a moving unit that moves around the patient.

The surveillance camera 20 is a camera for monitoring the radiation therapy device 10 and the patient. More specifically, the surveillance camera 20 captures an image of an imaging area set by the medical monitoring device 30. The surveillance camera 20 then transmits the captured image data to the medical monitoring device 30.

The medical monitoring device 30 determines whether or not there is a high possibility of interference between the radiation therapy device 10 and the patient during radiation therapy in the radiation therapy device 10. In other words, the medical monitoring device 30 determines whether or not the possibility of contact between the radiation therapy device 10 and the patient is equal to or greater than a threshold value.

Here, when a treatment plan for the radiation therapy device 10 is created, an interference simulation is performed before treatment to confirm that the radiation therapy device 10 does not interfere with the patient. In this interference simulation, it is predicted whether a patient model, which is a model of a virtual patient, will interfere with a radiation therapy device model, which is a model of a virtual radiation therapy device 10. More specifically, the interference simulation predicts whether the patient model will interfere with the moving part of the radiation therapy device model when the moving part of the radiation therapy device model is moved according to the treatment plan. Furthermore, the interference simulation predicts a numerical value indicating the possibility of interference between the patient and the radiation therapy device 10. Note that the interference simulation is not limited to the interference between the patient model and the moving part of the radiation therapy device model, but may also predict interference with other parts of the radiation therapy device model.

In this way, by performing an interference simulation, a treatment plan is created in which there is no interference between the patient and the radiation therapy device 10. However, during treatment, the position and posture of the patient placed on the bed 16 of the radiation therapy device 10 (see Figure 2) differs from the position and posture of the patient model in the interference simulation performed in advance. Therefore, medical personnel need to monitor to ensure that there is no interference between the radiation therapy device 10 and the patient.

The medical monitoring device 30 then corrects the position and posture of the patient model in the interference simulation based on image data capturing the position and posture of the patient placed on the bed 16 of the radiation therapy device 10. The medical monitoring device 30 also uses the corrected patient model to determine whether or not there is a high possibility of interference between the radiation therapy device 10 and the patient. The medical monitoring device 30 then controls the monitoring camera 20 based on the prediction result to display areas of high probability of interference. The medical monitoring device 30 also notifies the user of the prediction result by displaying it on the display 33 (see FIG. 3).

Next, the external appearance of the radiation therapy device 10 will be described. FIG. 2 is a diagram showing an example of the radiation therapy device 10 according to the first embodiment. The radiation therapy device 10 has a bed 16, a radiation generator 171 that generates radiation for treatment, a radiation constrictor 172, and a rotating gantry 19. The radiation therapy device 10 moves the bed 16, the radiation generator 171, the radiation constrictor 172, the rotating gantry 19, etc. in accordance with a treatment plan to perform radiation therapy. The radiation therapy device 10 is connected to a radiation therapy planning device (not shown), and performs radiation therapy by irradiating radiation from the radiation generator 171 to a treatment target area in accordance with a treatment plan transmitted from the radiation therapy planning device.

The radiation therapy device 10 further includes a radiation generator 181 that irradiates radiation for imaging, and a detector 182 that detects radiation for imaging. Before the start of radiation therapy, the radiation therapy device 10 irradiates radiation from the radiation generator 181 to the patient while rotating the rotating gantry 19, and the detector 182 detects the radiation that has passed through the patient. The radiation therapy device 10 then generates a CT image based on the detection result by the detector 182, and displays it on the display 12. This allows the user of the radiation therapy device 10 to confirm the position of the area to be treated at the start of radiation therapy. The radiation generator 171, the radiation aperture 172, the rotating gantry 19, the radiation generator 181, and the detector 182 are examples of a moving unit.

Figure 3 is a diagram showing an example of the configuration of the medical monitoring device 30 according to the first embodiment. As shown in Figure 3, the medical monitoring device 30 according to the first embodiment has a communication interface 31, an input interface 32, a display 33, a memory circuit 34, and a processing circuit 35.

The communication interface 31 is connected to the processing circuit 35 and controls the transmission and communication of various data between each device connected via the network. For example, the communication interface 31 is realized by a network card, a network adapter, a NIC (Network Interface Controller), etc.

The input interface 32 is connected to the processing circuit 35 and converts the input operation received from the operator (medical worker) into an electrical signal and outputs it to the processing circuit 35. Specifically, the input interface 32 converts the input operation received from the operator into an electrical signal and outputs it to the processing circuit 35. For example, the input interface 32 is realized by a trackball, a switch button, a mouse, a keyboard, a touchpad that performs input operations by touching the operation surface, a touch screen in which the display screen and the touchpad are integrated, a non-contact input circuit using an optical sensor, and a voice input circuit. Note that in this specification, the input interface 32 is not limited to only those that have physical operation parts such as a mouse and a keyboard. For example, an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the device and outputs this electrical signal to a control circuit is also included as an example of the input interface 32.

The display 33 is connected to the processing circuit 35 and displays various information and image data output from the processing circuit 35. For example, the display 33 is realized by a liquid crystal display, a CRT (Cathode Ray Tube) display, an organic EL display, a plasma display, a touch panel, etc.

The memory circuitry 34 is connected to the processing circuitry 35 and stores various data. The memory circuitry 34 also stores various programs that the processing circuitry 35 reads out and executes to realize various functions. For example, the memory circuitry 34 is realized by a semiconductor memory element such as a random access memory (RAM) or a flash memory, a hard disk, an optical disk, etc.

The processing circuitry 35 controls the operation of the entire medical monitoring device 30. The processing circuitry 35 has, for example, an input function 351, an acquisition function 352, an association function 353, an interference prediction function 354, a camera control function 355, and a display control function 356. In the embodiment, each processing function performed by the components of the input function 351, the acquisition function 352, the association function 353, the interference prediction function 354, the camera control function 355, and the display control function 356 is stored in the memory circuitry 34 in the form of a program executable by a computer. The processing circuitry 35 is a processor that realizes the function corresponding to each program by reading and executing the program from the memory circuitry 34. In other words, the processing circuitry 35 in a state in which each program has been read has each function shown in the processing circuitry 35 in FIG. 3.

In FIG. 3, the input function 351, acquisition function 352, association function 353, interference prediction function 354, camera control function 355, and display control function 356 are realized by a single processor, but the processing circuit 35 may be configured by combining multiple independent processors, and each processor may realize the functions by executing a program. Also, in FIG. 3, the processing circuit 35 may be configured to store a program corresponding to each processing function, but multiple storage circuits may be distributed and the processing circuit 35 may read out the corresponding program from each storage circuit.

The term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), a GPU (Graphical Processing Unit), an Application Specific Integrated Circuit (ASIC), a programmable logic device (e.g., a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA)). The processor achieves its functions by reading and executing a program stored in the memory circuit 34. Note that instead of storing a program in the memory circuit 34, the processor may be configured to directly incorporate the program into its circuitry. In this case, the processor achieves its functions by reading and executing a program embedded in the circuitry.

The input function 351 accepts input of a treatment plan for the radiation therapy device 10. The treatment plan is information such as the radiation quality, incidence direction, irradiation field, dose, and number of irradiations of the radiation used in radiation therapy. The radiation therapy device 10 moves the bed 16, radiation generator 171, radiation aperture 172, radiation generator 181, detector 182, rotating gantry 19, etc. in accordance with the treatment plan.

The acquisition function 352 acquires position information indicating the position of the patient on the bed 16. The acquisition function 352 is an example of an acquisition unit. Here, the position and posture on the bed 16 of the patient placed on the bed 16 differ from the position and posture on the bed 16 of the patient model in the interference simulation performed in advance. Therefore, even if it is determined that there will be no interference in the interference simulation performed in advance at the stage of creating the treatment plan, there is a possibility that interference will occur in the actual radiation therapy performed by the radiation therapy device 10. Therefore, it is necessary to improve the accuracy of the interference simulation.

To improve the accuracy of the interference simulation, it is necessary to correct the position and posture of the patient model in the interference simulation based on the position and posture of the patient on the bed 16. Therefore, the acquisition function 352 acquires position information indicating each part of the patient on the bed 16. In other words, the position information is information such as three-dimensional coordinates indicating the position of each part of the patient.

More specifically, the acquisition function 352 acquires position information based on image data captured by the surveillance camera 20, which captures images of the patient and the radiation therapy device 10. Specifically, the acquisition function 352 detects each part of the patient from the image data captured by the surveillance camera 20. For example, the acquisition function 352 detects each part of the patient by detecting a marker that serves as a landmark attached to each part of the patient from the image data. The marker is, for example, an instrument such as a reflector, or a printed matter with a pattern printed on it. That is, the acquisition function 352 detects each part of the patient by detecting a reflector or a pattern from the image data.

Then, the acquisition function 352 acquires position information indicating the three-dimensional position of each detected part. Specifically, the acquisition function 352 acquires the position information based on the positional relationship between the surveillance camera 20 and the radiation therapy device 10 in the image data, the pixel values of the image data, the position and angle information of each part such as the bed 16 acquired from the radiation therapy device 10, and the position of the marker attached to the patient. That is, the acquisition function 352 acquires the position information by calculating the three-dimensional coordinates of each part relative to a reference position based on this information.

The acquisition function 352 may detect each part of the patient by other methods, not limited to markers. For example, the acquisition function 352 detects the position and shape of the patient by detecting each part of the patient using a skeleton detection technique that detects the skeleton of a person included in the image data. The acquisition function 352 may also acquire position information indicating the position of the patient on the bed 16 by other methods, not limited to image data. For example, if the medical monitoring system 1 is equipped with a three-dimensional scanner that detects objects on the bed 16, such as a ToF (Time of Flight) sensor pointed at the bed 16, the acquisition function 352 may acquire position information indicating the position of the patient on the bed 16 based on the output from the three-dimensional scanner.

The association function 353 associates each part of the patient model in the interference simulation with each part of the patient indicated by the position information acquired by the acquisition function 352. Specifically, the association function 353 associates the part of the patient indicated by the position information with the part of the patient model in the interference simulation.

The interference prediction function 354 predicts the possibility of interference between the patient and the radiation therapy device 10 based on the position information. The interference prediction function 354 is an example of a prediction unit. More specifically, the interference prediction function 354 predicts the possibility of interference between the patient and the radiation therapy device 10 by correcting the position of a patient model in an interference simulation that predicts the possibility of interference between the patient and the radiation therapy device 10 having a moving part that moves around the patient based on the position information. That is, the interference prediction function 354 corrects the position of each part of the patient model in the interference simulation to the position of the patient on the bed 16 based on the position information.

The interference prediction function 354 also registers that each part of the patient model is in the corrected position, and then executes the interference simulation again. This allows the interference prediction function 354 to predict the possibility of interference between the patient and the radiation therapy device 10. Note that the interference prediction function 354 may correct the results of an interference simulation executed in advance based on the position information, without executing the interference simulation. Even in this case, the interference prediction function 354 can predict the possibility of interference between the patient and the radiation therapy device 10.

Furthermore, when the interference prediction function 354 determines that there is a high possibility of interference between the patient and the radiation therapy device 10, it generates interference position information indicating the three-dimensional coordinates of the interference location where there is a high possibility of interference between the patient and the radiation therapy device 10. The interference location is, for example, each part of the patient and the radiation therapy device 10 that is determined to be highly likely to interfere. For example, when there is a high possibility of interference between the patient's arm and the radiation generator 171, at least one of the patient's arm and the radiation generator 171 becomes the interference location. Note that the interference location is not limited to each part of the patient and the radiation therapy device 10 that is determined to be highly likely to interfere, but may be a position that is determined to be highly likely to interfere.

The camera control function 355 controls the surveillance camera 20 to capture image data of the specified imaging area. Specifically, the camera control function 355 controls the orientation, focus, and magnification of the surveillance camera 20 to capture image data of the specified imaging area.

More specifically, the camera control function 355 aims the surveillance camera 20 at an interference location where there is a high possibility of interference between the patient and the radiation therapy device 10 based on the prediction result by the interference prediction function 354. The camera control function 355 is an example of a camera control unit. That is, the camera control function 355 sets the position specified by the interference position information in the imaging area of the surveillance camera 20. As a result, the camera control function 355 causes the surveillance camera 20 to capture image data of the interference location.

Furthermore, when an object to be imaged by the surveillance camera 20 is registered in advance, the camera control function 355 sets the imaging area of the surveillance camera 20 so that the pre-registered object is included. For example, when it is registered to check a respiratory monitor indicator that detects the level of body movement at two locations in the chest and abdomen due to the patient's breathing, the camera control function 355 sets the imaging area of the surveillance camera 20 to the respiratory monitor indicator.

The display control function 356 causes the display 33 to display various screens. For example, the display control function 356 causes the display 33 to display image data captured by the surveillance camera 20. The display control function 356 also causes the display 33 to display a screen showing the simulation results of the interference simulation.

More specifically, the display control function 356 displays an interference location where there is a high possibility of interference between the patient and the radiation therapy device 10 based on the prediction result by the interference prediction function 354. The display control function 356 is an example of a display control unit. For example, the display control function 356 displays image data of the interference location captured by the surveillance camera 20. That is, when the interference location is set in the imaging area of the surveillance camera 20 by the camera control function 355, the display control function 356 displays image data of the interference location included in the imaging area set by the camera control function 355.

Alternatively, the display control function 356 displays the interference location on the interference simulation screen of the patient model in the corrected position. That is, the display control function 356 displays the interference location on the simulation screen. Note that the display control function 356 is not limited to displaying either the image data screen or the simulation screen, and may display both the image data screen and the simulation screen.

The display control function 356 highlights the interference areas. FIG. 4 shows an example of a highlighting screen in which the interference areas are highlighted. As shown in FIG. 4, the display control function 356 adds an interference mark 3561 to the image data by overlay. As a result, the display control function 356 highlights and displays the interference areas. Note that the highlighting method is not limited to adding the interference mark 3561, but may also be to make the interference areas blink, change the color, add a line to cover the interference areas, or use other methods.

The display control function 356 also displays a screen notifying the user that there is a high possibility of interference between the patient and the radiation therapy device 10 based on the prediction result. For example, the display control function 356 displays a message, a warning screen, or an icon indicating that there is a high possibility of interference between the patient and the radiation therapy device 10.

Here, when a target to be imaged by the monitoring camera 20 is registered, the camera control function 355 aims the monitoring camera 20 so that the designated target is included in the imaging area. Then, the display control function 356 displays the image data captured by the monitoring camera 20 on the display 33. Here, FIG. 5 is a diagram showing an example of a display screen for image data of the designated imaging area. As shown in FIG. 5, when displaying the respiratory monitor indicator is registered in the treatment plan, the display control function 356 displays the image data of the respiratory monitor indicator captured by the monitoring camera 20. Furthermore, the display control function 356 adds and displays a designated area mark 3562 indicating the designated imaging area. This allows the medical staff to recognize the area to be noted in the image data. Furthermore, since the imaging area is specified, the display control function 356 can display the image data of the respiratory monitor indicator even if the medical staff does not input an operation to display the respiratory monitor indicator.

Next, the pre-planning process and the interference detection process executed by the medical monitoring device 30 will be described. The pre-planning process is a process for executing an interference simulation according to a treatment plan. The interference detection process is a process for correcting the position of each part of the patient model in the interference simulation and determining whether or not there is a high possibility that each part in the corrected position will interfere with the radiation therapy device 10.

Figure 6 is a flowchart showing an example of a pre-planning process executed by the medical monitoring device 30 according to the first embodiment.

The interference prediction function 354 executes an interference simulation according to the treatment plan (step S11). That is, the interference prediction function 354 confirms through the interference simulation that the patient model and the radiation therapy device model do not interfere with each other when the moving part of the radiation therapy device model is moved according to the treatment plan.

The interference prediction function 354 stores the results of the interference simulation in the memory circuitry 34 or the like (step S12). Here, in the pre-planning process, a treatment plan is generated in which there is no interference between the patient and the radiation therapy device 10. The display control function 356 may also display on the display 33 that there is no interference between the patient and the radiation therapy device 10.

The medical monitoring device 30 then completes the pre-planning process.

Figure 7 is a flowchart showing an example of an interference detection process performed by the medical monitoring device 30 according to the first embodiment.

The acquisition function 352 acquires image data of a patient placed on the bed 16 of the radiation therapy device 10 (step S21).

The acquisition function 352 detects each part of the patient on the bed 16 contained in the image data (step S22).

The acquisition function 352 acquires position information indicating each detected part of the patient (step S23).

The association function 353 associates each part of the patient model in the interference simulation with each part of the patient indicated by the position information acquired by the acquisition function 352 (step S24). Note that the association function 353 may previously associate each part of the patient model with each part of the patient. By making the association in advance in this manner, the association function 353 can reduce the processing time required for the association.

The interference prediction function 354 corrects the position of each part of the patient model in the interference simulation to match the detected position of each part of the patient (step S25).

The interference prediction function 354 predicts the possibility of interference between the patient and the radiation therapy device 10 at the corrected position of each part (step S26). Based on the prediction result, the interference prediction function 354 determines whether or not there is a high possibility of interference (step S27). If there is a low possibility of interference (step S27; No), the medical monitoring device 30 proceeds to step S30.

If there is a high possibility of interference (step S27; Yes), the display control function 356 displays a screen notifying the patient that there is a high possibility of interference between the patient and the radiation therapy device 10 (step S28).

The camera control function 355 changes the focus of the surveillance camera 20 based on the prediction result, causing the surveillance camera 20 to capture an image of the interference area (step S29). Here, during treatment with the radiation therapy device 10, the surveillance camera 20 captures images of the patient and any area including the radiation therapy device 10 for monitoring by a medical professional. However, if it is determined that there is a high possibility of interference, the camera control function 355 controls the position, angle, magnification, focus, etc. of the surveillance camera 20 based on the prediction result in order to capture an image of the interference area. In this way, the camera control function 355 causes the surveillance camera 20 to capture an image of the interference area.

The medical monitoring device 30 determines whether or not the treatment by the radiation therapy device 10 has ended (step S30). If the treatment has not ended (step S30; No), the medical monitoring device 30 proceeds to step S21.

When the treatment is completed (step S30; Yes), the medical monitoring device 30 ends the interference detection process.

As described above, according to the medical monitoring device 30 of the first embodiment, the acquisition function 352 acquires position information indicating the position of the patient on the bed 16 of the radiation therapy device 10. The interference prediction function 354 corrects the position of the patient model of the interference simulation based on the patient position information, and uses the corrected patient model to execute an interference simulation to predict whether or not there is a high possibility of interference between the patient and the radiation therapy device 10. Then, the display control function 356 displays the interference points where there is a high possibility of interference between the patient and the radiation therapy device 10 based on the prediction result by the interference prediction function 354. Therefore, medical personnel can confirm the interference points where there is a high possibility of interference by looking at the screen displayed by the medical monitoring device 30. As described above, the medical monitoring device 30 can reduce the monitoring burden for interference between medical equipment and the patient.
