In the present invention, the registered content display means 16 is provided on the output side of the operation content storage means 10, and the output side of the registered content display means 16 connects the scan converter 6 and the D / A. An image / character information superimposing means 17 is provided between the converter and the converter 7.

The data is sent to the D / A converter 7 described above.

Next, the operation of the ultrasonic diagnostic apparatus configured as described above will be described. First, in FIG. 1, the probe 2 is brought into contact with the body surface of the subject 1, and ultrasonic waves are transmitted toward the internal diagnostic site. At this time, the ultrasonic waves emitted from the probe 2 are controlled by the transmission delay circuit in the ultrasonic transmission / reception circuit 3 so as to form a thin beam at the diagnosis site. The reflected wave from the diagnostic region is received by the same probe 2 and is taken in via the amplifier, the wave receiving delay circuit and the adder in the signal processing circuit 4, and a reception beam is formed. And from the above probe 2,
Transmission / reception is repeatedly performed so that the ultrasonic transmission / reception direction is sequentially changed at a predetermined cycle to ultrasonically scan a diagnostic region.

The ultrasonic signal (echo signal) output from the ultrasonic transmitting / receiving circuit 3 is input to the signal processing circuit 4,
The delay time is controlled with respect to the received echo signals of each channel so that the focus is optimal at the depth observed by the internal phasing circuit, and the phases are combined. The phase-combined received echo signal is subjected to sensitivity adjustment by the gain control circuit in the signal processing circuit 4. The received echo signal has a dynamic range of, for example, 60 to 90 dB, but the display 8 usually has a range of 20 to 30.
Since there is only a dynamic range of about dB, the built-in log amplifier circuit and dynamic range setting circuit set the optimum compression ratio. Further, the built-in full-wave rectifier circuit and envelope circuit remove the carrier component of the high-frequency received echo signal.

The received echo signal output from the signal processing circuit 4 is converted into a digital signal by the A / D converter 5 and input to the scan converter 6. The scan converter 6 has a plurality of line memories and an image memory, and the main controller 9 switches each time the ultrasonic wave transmission / reception direction changes to control writing and reading to and from the line memory, and sends the line memory to the image memory. The echo signals input to the image memory are sequentially written for each ultrasonic beam so as to form one ultrasonic tomographic image corresponding to the transmitting and receiving directions thereof. At this time, when the ultrasonic scanning for one image is completed by the control of the ultrasonic transmitting / receiving circuit 3, the probe 2 returns the scanning direction to the initial direction again and repeats the transmitting / receiving of the ultrasonic waves, Scanning is performed by sequentially changing each transmission and reception.

On the other hand, in the multi-operation control section 15, the operation panel 12 consisting of various control means such as keys, switches and volume controls the B mode, M mode,
It is used to set various inspection modes such as color Doppler mode, inspection conditions such as display depth, display screen and focus depth, or image conditions such as dynamic range, enhance and frame correlation. Normally, operation panel 1
Since the various control means on 2 are arranged in a matrix, it recognizes which key or switch is selected by the panel I / F circuit 13 and transfers it to the panel controller 14 of the next stage. With this panel controller 14,
The signal input from the operation panel 12 is transferred to the main controller 9 or vice versa.
Based on the information received from the control panel 12, when a key or a switch on the operation panel 12 is pressed, a reception process of whether or not the function is executed and a control such as turning on the key are performed.

Here, in a screening test or the like in which the inspection procedure is determined in advance, when one unit is a unit for recording one or more operation contents necessary for drawing an arbitrary image, The operation contents for a plurality of steps necessary for rendering a plurality of images are recorded in the operation contents storage means 10 by using the multi-operation operation means 11 or a menu operation. At this time, as the operation content in one step recorded in the operation content storage means 10, for example, as shown in FIG. 2, the operation item to be operated at the time of the screening test is the first operation according to the order of the operation order. , The second operation, the third operation, ... Are recorded, and the parameter value for each operation item is also recorded. Then, in the case of recording the above operation contents by using the menu operation, for example, the operation items and the parameter values may be registered in the order as shown in FIG.

When recording the operation contents by using the multi-operation operating means 11 shown in FIG. 1, after setting the entire apparatus in the recording state, the operation is performed in accordance with the actual operation procedure. The operation item for each step and its final parameter value may be automatically recorded. As items to be recorded, not only the setting state of the device but also the start step and the end step of timer display may be recorded. The timer display can display the elapsed time from an arbitrary step on the display 8, and is useful for an examination for examining the progress after drug administration or exercise load. Moreover, after adding a measurement function and image recording to an external image recording device, after setting a series of modes to draw the target image, it will automatically execute the measurement function and image recording when frozen. You may Regarding the above image recording,
The operation may be performed immediately after the multi-operation operating means 11 is operated, and then the freeze may be automatically released to execute a series of mode settings. At this time, depending on the image recording apparatus, a fixed waiting time may be set without releasing the freeze immediately after the image is recorded, and the freeze may be released after the waiting time. Furthermore, a comment display function may be provided so that the recorded comment is always displayed when the multi-operation operation is executed, or may be displayed only for a certain period of time. In the display for a certain period of time, even if the number of types of multi-operations increases, it is possible to instantly determine which image is the step to be rendered by displaying a comment regarding the image of interest in each step.

Then, the confirmation of the registered operation contents is as follows.
This is performed by various control means on the operation panel 12. When the panel key for displaying the registered content is selected, the panel I / F circuit 62 recognizes it, and transfers the panel key recognized by the panel controller 14 to the main controller 9. The main controller 9 displays the registered content. Transfer control to means 16. Then, the registered content display means 16 reads the content registered in the operation content storage means 10, creates and outputs the character information in the format as shown in FIG. At this time, if you display an example of the items and parameters that are actually output,
As shown in FIGS. 4 and 5. After that, when the above example is displayed, it becomes as shown in FIGS. 4 and 5. Then, the character information output from the registered content display means 16 is input to the image / character information superimposing means 17 and is superimposed on the image information output from the scan converter 6. The superimposed data is converted into an analog signal by the D / A converter 7 and sequentially sent to the display 8. And the display 8 is
The input video signal is brightness-modulated and displayed as an image.

FIG. 6 is a block diagram showing a second embodiment of the present invention. In this embodiment, the parameter value of each operation item is set on the output side of the operation content storage means 10 in an optimum order based on the operation content stored for each step by the multi-operation operation means 11 at the time of execution. While the execution procedure setting means 18 for executing the execution is provided, the output from the execution procedure setting means 18 is input to create character information for displaying the items of the execution procedure under the control of the main controller 9 Display means 1
9 is provided. In the operation content storage means 10 output to the execution procedure setting means 18, the parameter values of each operation item in the final state of each step in rendering an arbitrary image are recorded, and at the time of execution, by the multi-operation operation means 11. Based on the operation contents stored for each step, the execution procedure setting means 18 executes the operation while setting the parameter values of the operation items in the optimum order as shown in FIG. Also, the execution content display means 1
9 inputs the output from the execution procedure setting means 18,
Under the control of the main controller 9, character information with a mark (for example, an asterisk mark "*") for confirming whether or not the item of the execution procedure has become the registered parameter is shown in FIG. Create and output to. Then, the output character information is superimposed on other information by the image / character information superimposing means 17 and displayed on the display 8. At this time, not only the item name but also the parameter may be displayed at the same time as the item to be displayed.

In the embodiment shown in FIG. 6, the optimum execution procedure is preset by the execution procedure setting means 18 with respect to the recorded parameter values of the operation items. At the time of execution, by performing all the operations in order according to the set procedure, it becomes possible to set the mode for obtaining the target image. For example, taking the step 2 shown in FIG. 4 as an example, when the multi-operation operating means 11 is executed, (1) an image is recorded in an image recording device (eg printer). (2) Set the number of display screens to "1 screen". (3) Two image memories L and R in the scan converter 6
The image in the “L side” image memory is displayed. (4) Set the inspection mode to "B mode". (5) Set the display depth to "12 cm". (6) Set the entire image to 1 so that the display start depth becomes “10 mm”.
Shift up 0 mm. (7) Select the body mark shown in the figure. (8) Display the comment “GB” on the screen of the display unit 8. (9) After the mode setting is completed and the desired image is drawn, press the Freeze key to make the image stand still,
"Area" measurement is automatically performed. Each operation item is executed one after another in this procedure. This figure 4
As shown in FIG. 5, there is a method of recording all the final states set for each step by item, but, for example, as shown in FIG. 5, only items whose states are different between the steps of FIG. 4 are recorded. A difference recording method may be adopted.

FIG. 9 is a block diagram showing a third embodiment of the present invention. According to this embodiment, the multi-operation operating means 11 is used between the operation content storing means 10 and the execution procedure setting means 18 to select the previous step from all items of each step registered in the operation content storing means 10. And a registered content comparing means 20 for selecting and outputting a parameter different from the parameter recorded in the step to be executed next. The registered content comparison means 20
Is the parameter recorded in the previous step and the step to be executed next from all items of each step recorded in the operation content storage means 10 by using the multi-operation operating means 11. Select the different one and output it to the execution procedure setting means 18. The execution procedure setting means 18 creates the execution procedure of the item to be executed, which is received from the registered content comparison means 20, according to the preset execution procedure of all the items. Thus, instead of executing all the items output from the operation content storage means 10, by using the registration content comparison means 20, only the items that are different from each other by comparing the registration state with the previous step. The method of executing is called the differential execution method. At this time, the recording to the printer other than the mode setting, the automatic execution function of the measurement item, and the like are executed as they are regardless of the difference execution method.

For example, the multi-operation operating means 1
When the setting condition of each step recorded in the operation content storage means 10 is executed by 1, the difference of the setting state between each step is compared by the function of the registered content comparison means 20 and Then, the execution procedure setting means 18 creates an execution procedure, and the procedure similar to each step shown in FIG. 5 is executed according to this execution procedure. When comparing the states,
Regarding the mode setting, different items and conditions between each step are selected as execution targets, but it is decided whether or not to execute measurement items and image recording in each step. Become.

Step 2 (1) Record an image on the printer. (2) Set the entire image to 1 so that the display start depth is "10 mm".
Shift up 0 mm. (3) For the body mark, select the same one as shown in step 2 of FIG. (4) Display the comment “GB” on the screen of the display unit 8. (5) When the freeze key is pressed to freeze the image after the target image has been drawn, "area" measurement is automatically executed.

Step 3 (1) Record an image on the printer. (2) Set the number of display screens to "2 screens". (3) Shift the entire image downward so that the display start depth becomes "0 mm". (4) As the body mark, the same one as shown in step 3 of FIG. 5 is selected. (5) Display the comment “R-Kidney” on the screen of the display unit 8. (6) When the freeze key is pressed to freeze the image after the target image has been drawn, the "distance" measurement is automatically executed.

Step 4 (1) Two image memories L and R in the scan converter 6
The image in the “L side” image memory is displayed. (2) For the body mark, select the same one as shown in step 4 of FIG. (3) Display the comment "L-Kidney" on the screen of the display unit 8. (4) When the freeze key is pressed to freeze the image after the target image has been drawn, the "distance" measurement is automatically executed. Steps 5 and subsequent steps are the same as those shown in FIG.

Next, when confirming the execution state, the execution procedure setting means 18 shown in FIG.
The execution state confirmation means 21 confirms whether or not the item executed via the main controller 9 has become a parameter to be actually changed. It should be noted that the execution status confirmation means 21 includes the main controller 9 and the execution content display means 19
It is provided between and. After the execution status confirmation means 21 confirms, the execution content display means 19 displays the items to be executed by the differential execution method output from the execution procedure setting means 18, and the execution status output from the execution status confirmation means 21. Based on, the character information as shown in FIG. 7 is created and output. At this time, as the character information output by the execution content display means 19, as shown in FIG. 8, a combination of the item name to be changed and its parameter may be displayed. Then, when the execution contents are displayed when the step 4 is executed differentially, it becomes as shown in FIG. 10, and the displayed item is an item to be executed, for example, an item without an asterisk mark "*". The parameter value that should be set could not be set due to the image condition at the time of execution. With such a differential execution method, only different condition settings are executed, so that the execution time between steps can be shortened.
