For example, it comprises a television monitor. The D / A converter 9 and the display 10 serve as an image display unit that displays the image signal generated by the image processing unit as an image.

The operation control unit 11 is for inputting various operation commands and measurement conditions and the like, and has an operation panel 13, a two-dimensional position setting means 14, a panel interface circuit 15, and a panel controller 16. And. The operation panel 13 has a B mode or an M mode,
It sets various inspection modes such as color Doppler mode, inspection conditions such as display depth or focus setting, and image processing conditions such as dynamic range or enhance and frame correlation. Various operation keys are arranged in a matrix. .

When the mode is selected, the function with the highest priority in the measurement mode selected last is forcibly set to rank 1. For the other measurement modes, the rank of the function to be used is specified by progressively lowering according to the basic priority above. It is supposed to do.

For example, as shown in FIG. 2, it is assumed that there are eight kinds of use functions given to the two-dimensional position setting means 14 in the vertical columns of the table shown in FIG. Basic priority levels 1, 2, 3, ..., 8 are set in advance in order. In other words, the basic priority is 1st, "probe mark position setting," and 2nd is "vertical movement amount setting."
The 8th place is "setting of cursor for measurement".
Further, as various measurement modes of the ultrasonic diagnostic apparatus, it is assumed that there are eight kinds of modes described in the column next to the table shown in FIG.
When any of these various measurement modes is selected, the highest priority use function in that mode is set as indicated by the circles in the figure. That is, when the "body mark" mode is selected, the use function of the two-dimensional position setting means having the highest priority in that mode is "probe mark position setting", and when "B mode" is selected, that mode is selected. The highest-priority use function in "is the setting of the amount of vertical movement", and ... When the "Measurement function" mode is selected, the highest-priority use function in that mode is "Measurement cursor setting" . In this way, by setting the highest-priority use function in each measurement mode, the highest-priority use function in the last-selected measurement mode is forcibly forced when various measurement modes are arbitrarily selected. The order of the function to be used can be designated by sequentially lowering the order of the other measurement modes in accordance with the above basic priority order. The priority setting means 18 is also connected to the panel controller 16 of the operation control section 11.

The used function switching means 19 switches a plurality of used functions provided to the two-dimensional position setting means 14, and is composed of, for example, one paddle switch,
Each time the lever is tilted to the left or right, the function to be used is switched in order of priority.

Further, the use function display means 20 displays the use function of the two-dimensional position setting means 14 in the priority order determined by the priority order setting means 18 on the display 10 of the image display section.
Are displayed by letters or marks, and the marks of the used function of the first priority are alternately arranged on both sides of the mark of the used function, and the output signal is output. The information is sent to the information display means 6. As the characters and marks that display the above functions,
For example, as shown in FIG. 3, for the function to be used, which is "Set probe mark position", the characters "PBM
“ARK” is displayed, and the graphic described below is displayed as a mark. In addition, for the function to be used called "beam line setting", "M-BEAM" is displayed as a character, and the graphic described below is displayed as a mark. Further, for the use function of "setting of cursor for measurement", "MEASURE" is displayed as a character, and the graphic described below is displayed as a mark. The character and mark data for displaying, for example, eight kinds of used functions are recorded in the used function display means 20, and are read out and output when the used function is selected. Has become.

Next, the operation of the ultrasonic diagnostic apparatus configured as described above will be described. First, with the probe 1, the subject 1
7, an ultrasonic wave is transmitted and received, the reflected echo signal obtained thereby is amplified by the ultrasonic wave transmitting and receiving circuit 2, and then the signal processing circuit 3, the A / D converter 4, the scan converter 5, the image / character information superimposing means. 7. Displaying an ultrasonic image on the display 10 via the D / A converter 9 is performed in exactly the same manner as a normal ultrasonic diagnostic apparatus. Therefore, here, the operations of the operation control unit 11, the priority setting unit 18, the used function switching unit 19, and the used function display unit 20 will be mainly described.

First, by using the operation panel 13 of the operation control unit 11, various inspection modes such as B mode, M mode, and color Doppler mode are set, inspection conditions such as display depth or focus are set, and dynamic range is set. Alternatively, image processing conditions such as enhancement and frame correlation are set. At this time, since the operation keys and switches on the operation panel 13 are arranged in a matrix, the panel interface circuit 1 to which the operation signal is input is input.
5 recognizes which operation key or the like has been selected, and outputs the signal of the recognized operation key to the panel controller 1 in the subsequent stage.
Transfer to 6. When the panel controller 16 transfers an operation signal input from the operation panel 13 to the main controller 8 or conversely inputs information from the main controller 8 and a certain operation key on the operation panel 13 is pressed. To perform a reception process as to whether or not to execute the function, or to light the operation key.

On the other hand, the use function of the two-dimensional position setting means 14 corresponding to the various measurement modes set on the operation panel 13 is the basic priority preset by the priority setting means 18 and the highest priority in the various measurement modes. It is set as follows according to the ranking. That is, according to the ◯ mark shown in the table of FIG. 2, it is set to “probe mark position setting” in the case of “body mark” mode, and set to “vertical movement amount setting” in the case of “B mode”. And then "M
In the case of "Mode", it is set to "Beamline setting", in the case of "Doppler mode" it is set to "Sample point setting", and in the case of "Color Doppler (CFM) mode" it is "Color display range setting" , "Pan-Zoom" is set to "Region of interest setting", "Comment input" is set to "Comment cursor setting", and "Measurement function" is set to "Measurement cursor" Is set to.

The use function of the two-dimensional position setting means 14 set as described above is displayed on the corner of the screen of the display 10 via the use function display means 20. The display mode is
As described above, the characters and marks shown in FIG. 3 are displayed. And, the use function of the two-dimensional position setting means 14 is not usually one. For example, when "Doppler mode" and "color Doppler mode" are selected, "setting of sample point" and "color display range" are selected. It can be used for two usage functions such as "setting". In such a case, the use function switching means 19 connected to the priority setting means 18 can switch a plurality of use functions of the two-dimensional position setting means 14 according to the priority order given to them.

Now, with respect to the setting states of various modes, 2
FIG. 4 shows a usable state of a plurality of use functions of the dimension position setting means 14. In the table shown in FIG. 4, the setting contents of, for example, eight types of measurement modes are shown in the first half of the horizontal column,
In the latter half, for example, the usable states of the eight types of used functions are indicated by circles. Further, the numbers in the vertical columns indicate the mode numbers based on the combinations of the setting states of the above eight types of measurement modes. For example, as shown in the column of mode number 12, B mode, M mode, and Doppler mode (B /
M / D) is selected and color Doppler (CFM)
When the mode is selected, the pan-zoom is ON, and the comment input, the freeze, and the measurement function are OFF, the two-dimensional position setting means 14 has a use function of "probe mark position setting" marked with a circle. "Setting sample points"
And "Setting the color display range" and "Setting the region of interest"
And four functions are assigned.

At this time, if the color Doppler (CFM) mode is selected last in the selection of the various measurement modes, the measurement selected last in the combination of the basic priority and the highest priority shown in FIG. Forcibly set the highest priority function in the mode to 1
For the other measurement modes, the priority is sequentially lowered according to the basic priority order shown in FIG. No. 1 ... "Color display range setting" (highest priority) No. 2 "Probe mark position setting" (basic priority 1) No. 3 "Sample point setting" (basic priority 4) No. 4 "... Setting the area of interest "(Basic priority 6)

The signal of the use function of the two-dimensional position setting means 14 with the priority designated as described above is output from the priority setting means 18 to the use function display means 20, and then the character information display means 6 and the image / image display. It is sent to the display device 10 through the character information superimposing means 7 and is displayed at the corner of the screen as shown in FIG. That is, a mark indicating "color display range setting" of priority 1 is displayed near the center, and a mark indicating "probe mark position setting" of priority 2 is displayed on the left side of the mark, for example. A mark indicating "setting of sample point" of priority 3 is displayed to the right of the mark of 1st priority, and "setting of region of interest" of 4th priority is displayed to the left of the mark of 2nd priority. Is displayed. At this time, the mark with the first priority may be displayed in black and white in reverse, or may be displayed in different colors. In this way, it is possible to easily determine what the used function with the first priority is. In this state, the used function switching means 19 is operated to select a desired function from the four used functions, for example. After that, the two-dimensional position setting means 14 is operated in the selected use function to move and set a desired marking line (beam line, cursor, etc.) on the screen of the display 10.

Further, as shown in FIG. 5, since the marks of the used functions of the first and second priorities are alternately arranged on both sides of the mark of the used function of the first priority, it is displayed.
When the desired function to be used is selected by the use function switching means 19, even if the priority is changed from the first priority to the third priority, it is possible to quickly switch to the right by one operation. Further, even when switching from the first priority to the fourth priority, it is possible to quickly switch to the left by two operations.

As another embodiment of the use function display means 20, a display mark of a use function given the highest priority right and a marking line corresponding to the function to be displayed on the screen of the display 10 are specified. It may be displayed with the same color, and may be displayed in a different color from the function to be used which is not given the highest priority. That is, the display mark of the used function to which the highest priority right (priority No. 1) is given and the marking line corresponding to the function are displayed in yellow, for example, and the display mark of the used function to which the highest priority right is not given is displayed. The marking line corresponding to the function and the marking line are displayed in white, for example. By doing so, it is possible to instantly understand what the use function is given the highest priority by looking at the colored marking lines without looking at the mark display as shown in FIG.

Although the above description has been given by taking the ultrasonic diagnostic apparatus as a typical example as the medical image diagnostic apparatus, it can be similarly applied to other image diagnostic apparatuses. In this case, for example, in an X-ray imaging apparatus, the information carrier is an X-ray, the information carrier generation unit is an X-ray tube device, and the information carrier detection unit is a fluorescence amplification tube and a television camera. Also, X-ray C
