Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a medical diagnostic imaging device, such as a circulatory system X-ray diagnostic imaging device, which displays the status of numerous devices that make up the device on a CRT screen, and confirms whether or not they are ready for imaging. The present invention relates to a safety confirmation display device that makes it easy for the operator to access, clearly indicates the time when imaging can start, and that can respond immediately to the movement or change of the above-mentioned equipment.

In general, in an X-ray diagnostic apparatus, particularly in an X-ray diagnostic apparatus for circulatory organs including the heart, a number of devices as shown below are usually organically combined. For example, (1) two three-phase 12-pulse rectified high voltage generators, (2) X for fluoroscopy and cine imaging.
1 X-ray tube device, (3) 2 X-ray tube devices for continuous imaging in two directions at the same time, (4) X-ray tube device of (3) above for stereoscopic imaging, (5) Contrast medium injection device 1 (6) Two high-speed film changers, other cinepulse control equipment, a multi-element storage device for biological phenomena (electrocardiogram, intracardiac pressure, etc.), and an X-ray television system. It is very important to correctly confirm that all of these devices have been set up correctly in order to prevent erroneous operation and damage to the devices. Conventional safety confirmation display panels that display these setup statuses on the display panel have a pilot lamp installed inside each device shape drawn on the panel surface, and when the device is ready, a micro switch inside the device, for example, is activated. It was a simple process in which a lamp within the device figure on the panel surface was lit by the detection element and other detection elements. The line drawings on this panel surface are from the original layout, and cannot be easily changed in response to moving equipment or changing to other equipment, so it is not used in the circulatory system diagnostic room mentioned above. If equipment is moved or changed frequently, it may not be possible to respond immediately and follow the changes.
It has the disadvantage that it may become unusable immediately or may cause erroneous operation even if it is used.

The present invention has been made in view of the above-mentioned current situation, and is intended to solve the drawbacks of conventional display devices for medical diagnostic imaging systems. That is, a storage means for changeably storing the arrangement of each device of the diagnostic imaging system and its control system and its operation system, and a storage means for detecting the imaging preparation completion state of each of the devices and calculating and converting these detected event values. Arithmetic processing/signal transmission means for determining whether or not the diagnostic imaging system can be started and issuing a seal release signal for the control system when possible, and the memorized arrangement and operation system of each device and their imaging. This invention relates to a medical diagnostic imaging system safety confirmation display device, characterized in that it is provided with an output means for graphically displaying a preparation completion state on a CRT screen and displaying on the same screen that the diagnostic imaging system can be started.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration in which a safety confirmation display device according to an embodiment of the present invention is applied to a circulatory organ X-ray diagnostic imaging system. For example, a three-phase current 12-pulse high-capacity X-ray control device 1 controls imaging conditions such as tube voltage, tube current, and imaging time of the X-ray tube devices 2 and 3. In the figure, 2L, 3L, 4L, and 10L indicate these high voltage control lines. The X-ray tube device 2 is for photographing the subject M in the lateral direction, and the X-ray tube device 3, together with the X-ray tube device 4, is for taking stereoscopic photographs of the subject M from the front direction. The X-ray tube 4 is now controlled by one X-ray control device 5. The X-ray fluoroscopic images from the X-ray tube devices 2, 3, and 4 are produced at a high speed of 6 or more per second by the film chainers 7 and 8 controlled by the film chain program selector 6. Photographed on film. A contrast agent injection device 9 used for all types of angiography such as cardiovascular and lymphatic vessels is also linked with the program selector 6,
Inject the contrast agent at the appropriate timing. On the other hand, a fluoroscopic image obtained by an X-ray tube device 10 controlled by an X-ray controller 5 is converted into a visible light image by an image tube 11 and recorded by a cine camera 12 at a maximum of 200 frames/second, for example. . The above is an example of the configuration of a circulatory organ X-ray diagnostic imaging system, and the main part of the present invention is the configuration of each block within the frame of the dotted line 21. The layout storage section 22 is, for example, a rewritable semiconductor memory that stores the arrangement of each of the above-mentioned devices 1 to 12 and its operation system, and when changing the layout of the above-mentioned devices using the operation console 23, the stored contents can be easily changed. It is possible.
The computer 24 is configured so that a photographing preparation completion signal from each device is inputted through the single signal line shown in FIG. 1, and a detailed explanation will be given later. A graphic CRT display 25 is provided as an output device of the computer 24.
FIG. 2 shows a state in which the arrangement of the above-mentioned devices 1 to 12 is first displayed on the screen of the CRT 25 in the form of figures showing the characteristics of each device, and the operation system of each device is not displayed at all. Next, the operator completes setting of imaging conditions such as tube voltage, tube current, and time in the X-ray controller A1, and then positioning of the X-ray tube device 2 using the holder (not shown) is also performed by the operator. , and once the selection of large and small focal points is completed, the steps 1 and 2 above are completed.
A control line 2L is displayed on the screen, and at the same time, the characters (OK) are displayed near the figure 2. (3rd
), and when the film changers 7 and 8 are filled with magazines by the operator and the program selectors 6 are set to a predetermined program, the control lines 7L and 8L between 7 and 8 and 6 are is displayed, and at the same time the characters (OK) are displayed beside 7 and 8. In this way, each time the imaging preparatory conditions and preparatory state of each device are completed, the control operation system input from each device to the computer 24 and stored is displayed on the CRT 25 screen. Third
The figure shows when all the equipment is ready.
This is a CRT 25 screen, and the computer 24 determines the preparation completion status, and if it determines that it is possible to shoot,
A signal is issued to the line control devices A, B, 1, 5 and the film changer program selector 6 to release their interlocks (for example, a functionally sealed circuit using a relay). At the same time, dotted lines 2X, 3X, 4X, 1 from X-ray tube devices 2, 3, 4, 10
The 0X X-ray beam direction is displayed to visually indicate to the operator that X-ray exposure is possible. Unless the computer 24 confirms that the preparation is complete and cancels the interlock, the operator will not receive any X-rays even if the X-ray exposure switch is pressed.
Since no radiation is emitted, erroneous operation and equipment damage are completely prevented. Returning to FIG. 2 again, when moving the X-ray tube devices 3 and 4 for photographing the front of the subject for side-view photography, in other words, the X-ray tube device 2 is moved back to the position 2', and the X-ray tube is placed at that position. When the tube device 4 is moved and at the same time the 3 X-ray tube devices are moved to the position 3' by operating the holders (not shown), signals from those holders are input to the computer 24,
The CRT25 screen automatically displays the changed locations of 2, 3, and 4. Further, the control line 3L from the X-ray control device 1 is connected to the X-ray tube device 3', and the control line 4L from the X-ray control device 5 is connected to the X-ray tube device 4'.The subsequent operations are as described above.

The above is the configuration and operation of the display device of the present invention when applied to a circulatory organ X-ray diagnostic imaging device, but the present invention is not necessarily limited to the circulatory system, and is applicable to any of the urinary, digestive, and other organs. It can also be applied to diagnostic imaging equipment. The method of displaying CRT graphics is not limited to the illustration, and simple abbreviations may be given to the graphics. Further, the control system to be displayed when preparation is completed may also be displayed from the beginning.

Since this invention is configured as described above,
This eliminates the drawbacks of the line-drawing safety confirmation display panel used in conventional medical diagnostic imaging equipment. In other words, it not only memorizes the layout of all the diagnostic imaging equipment and their control equipment, and displays this graphically on the CRT screen, but also displays their readiness status to facilitate operator confirmation. When all equipment is ready, the computer determines that the sealing function of the X-ray control system and imaging equipment will be released, allowing the operator to start imaging, allowing double safety confirmation. , it is possible to completely prevent erroneous operations by the operator. Furthermore, it is possible to provide a convenient device that can easily change the display in response to movement of each device of the diagnostic imaging device or change of its model, and can always display an accurate layout.
