DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration example of an ultrasonic diagnostic apparatus as an example of the medical image diagnostic apparatus of the present invention, FIG. 2 is a flowchart showing an operation example of the ultrasonic diagnostic apparatus of FIG. 1, and FIGS. 3 to 6 are inputted FIG. 7 is a diagram showing an example of how to determine the priority used when displaying input elements.
[0009]
Each function of the ultrasonic diagnostic apparatus will be described with reference to FIG.
The ultrasonic diagnostic apparatus includes a probe 5, an ultrasonic transmission / reception unit 6 electrically connected to the probe 5, a phasing unit 7 electrically connected to the ultrasonic transmission / reception unit 6, and a phasing A digital scan converter (DSC) 8 electrically connected to the unit 7, an image composition unit 9 electrically connected to the DSC 8, a monitor 10 electrically connected to the image composition unit 9, and a console 1 A sensor 2 that is attached to each input element such as a key, a trackball, and a rotary encoder of the console 1, a controller 3 that is electrically connected to the output of each sensor 2, and a controller 3 that is electrically connected And a character generation unit 4. The controller 3 is also electrically connected to the DSC 8 and the image composition unit 9, and the character generation unit 4 is electrically connected to the image composition unit 9.
[0010]
The probe 5 contacts the subject and transmits an ultrasonic signal into the subject, and receives a reflected echo signal from the subject. The ultrasonic transmission / reception unit 6 applies a signal to the probe 5 so that the ultrasonic wave can be transmitted, and performs signal processing including amplification on the reflected echo signal received by the probe 5. The phasing unit 7 gives a predetermined delay to the reflected echo signal subjected to signal processing. The DSC 8 converts the reflected echo signal provided with a predetermined delay amount into various ultrasonic images such as a B mode image, an M mode image, and a color flow mapping image. The image synthesizing unit 9 synthesizes an ultrasonic image and an output of a character generating unit 4 described later as a synthesized image. The monitor 10 displays the synthesized image synthesized by the image synthesizing unit 9.
[0011]
In the console 1, an operator performs operation input to input elements. The sensor 2 is provided for each input element of the console 1. When a part of the operator's body (in this case, a hand or a finger) is beaten on the input element, the sensor 2 is beaten. Detect input elements. This sensor 2 detects that the operator has touched the hand, such as a photoelectric sensor that detects light being blocked by touching the hand, an infrared sensor that detects that infrared light hits the reflected hand and reflects it. Any sensor can be used as long as it is possible. The output of each sensor can identify individual sensors such as frequency, amplitude, and phase difference. Further, as shown in FIG. 7, a sensor attached to the input element is arranged so that the console 1 has a higher priority toward the upper side of the drawing. In other words, the detection output of the sensor where the operator's hand is deceived can be specified by the priority of each sensor.
[0012]
The controller 3 controls the character generation unit 4 based on the output from the identified sensor 2. The controller 3 controls other main elements of the ultrasonic diagnostic apparatus such as the DSC 8 and the image synthesis unit. The character generation unit 4 generates an enlarged schematic diagram or a message for information related to the input element controlled by the controller 3, and outputs the schematic diagram and message to the image composition unit 9. Detailed examples of schematic diagrams and messages are shown in the display examples of FIGS.
[0013]
FIG. 3 shows an example in which the rotary encoder 32 that adjusts the display gain (B gain) when the B mode image 31 is displayed on the screen 30 is specified. A message 33 “B gain” is displayed. , 35 indicates that it can be rotated in each direction.
[0014]
In FIG. 4, an ultrasonic image 41 is moving on the screen 40 in real time as a moving image. For this reason, a key 42 called “freeze” for obtaining a still image when an image for diagnosis is found is specified. At that time, a message 43 “Freeze” is displayed.
[0015]
In FIG. 5, when an ultrasonic image 51 is displayed on the screen 50 and the left and right sides of the image are to be reversed and displayed, the horizontally reversed key 52 is specified. At that time, a message 53 that indicates left-right reversal is displayed.
[0016]
In FIG. 6, when an ultrasonic image 61 is displayed on the screen 60 and it is desired to adjust the depth-specific gain of the display depth of the image, the depth-specific gain key 62 specifies. At that time, a message 63 of gain by depth is displayed.
[0017]
Moreover, although the example which displayed the input element which should be operated in the form which expands a schematic diagram is shown here, as a mode which shows the specified input element, the point which identified the input element is distinguishable, such as changing a color. Should be displayed as follows.
[0018]
Next, the operation of the ultrasonic diagnostic apparatus will be described with reference to FIG.
The operator places his hand on the console 1. The sensor 2 determines whether or not it has been deceived. This determination waits until the hand is touched, and when the hand is touched, the process proceeds to the next step (step 21).
[0019]
The controller 3 specifies an input element such as a key based on the priority of the output of the sensor 2 (step 22).
[0020]
The character generating unit 4 generates a schematic diagram such as the identified key or a message (step 23).
[0021]
The image composition unit 9 synthesizes the ultrasonic image output from the DSC 8 and the schematic diagram output from the character generation unit 4 to generate a composite image. The monitor 10 displays the composite image (step 24).
[0022]
As described above, according to the present embodiment, the console 1 has a plurality of input elements, and the operator's operation information is input by the input elements, and the operation information input to the console 1 is used. The medical image (ultrasonic image) of the subject is measured, and the medical image is displayed on the monitor 10 for image diagnosis. A part of the operator's body is placed on the console 1 A character generator 4 for generating operation information of the console 1 based on a position of an input element on the console 1 detected by the sensor 2; Since it includes a controller 3 that controls the image composition unit 9 so that the operation information of the input elements generated by the character generation unit 4 is displayed on the monitor 10 together with the medical image, it is complicated as in a conventional TV camera or the like. Simpler structure without using a simple mechanism It is possible to perform various operations from Nita screen without moving the line of sight.
[0023]
In the present embodiment, an ultrasonic diagnostic apparatus has been described as an example of a medical image diagnostic apparatus. However, any of those capable of measuring and diagnosing a medical image of a subject such as an X-ray fluoroscopic apparatus, an X-ray CT apparatus, and an MRI apparatus. It may be.
