In other words, the display unit includes a first display area that displays the measurement condition and a second display area that displays the ultrasonic image.

  The control unit 60 controls the ultrasonic image measurement unit 20 and the storage unit 40 (display unit 50) according to the parameters input to the input unit 10.

(First Embodiment) Setting of Line Feed Execution Parameters The first embodiment will be described with reference to FIGS.
2 is a flowchart for explaining an operation example of the first embodiment of the ultrasonic diagnostic apparatus of FIG. 1, FIG. 3 is a diagram showing an example of a display screen of measurement condition display / setting of S21 and S22 of FIG. 2, FIG. 2 is a flowchart for explaining the subroutine of the format generation process of S23 in FIG. 2, FIG. 5 is a diagram showing an example of setting the result frame in FIG. 4, and FIG. 6 shows the correspondence between the result frame table set in FIG. FIG. 7 is a diagram illustrating a display example when the measurement point setting / calculation process of S24 of FIG. 2 is performed and the measurement result display process of S25 is performed.

The operation of the first embodiment will be described according to the flowchart of FIG.
The control unit 60 reads a plurality of measurement conditions of the ultrasonic diagnostic apparatus stored in the storage unit 40 and displays them on the screen of the display unit 50. Specifically, the measurement conditions of the “measurement setup menu” are displayed in the window shown on the left side of the display screen shown in FIG. 3 (step S21).

  The operator uses the input unit 10 to select the measurement conditions for the measurement (distance D, perimeter length C, area A) from the measurement setup menu shown in FIG. Set. The control unit 60 displays the measurement conditions set in this way in the display format of other measurement conditions in black and white reversal, for example, in order to distinguish them from other measurement conditions that have not been set (step S22).

  The control unit 60 generates a display format related to the measurement conditions of Measurement. This display format generation processing is performed in steps S31 to S37 shown in FIG. 3 (step S23).

  The display format is formed with a two-dimensional matrix (X, Y) structure. Here, a display example of 4 rows and 4 columns will be described.

The control unit 60 initializes the two-dimensional matrix (X, Y) and the loop counter value to 1, respectively.
(Step S31).

  The control unit 60 determines whether or not X indicating a column of the two-dimensional matrix is larger than four columns. As a result of this determination, the control unit 60 proceeds to step S33 if X is smaller than 4 columns, and proceeds to step S34 if X is larger than 4 columns (step S32).

  The control unit 60 determines whether or not the “display at X1 (left end)” setting is ON. The operator uses the input unit 10 to set the display result frame (display format) to `` display on X1 (left end) '' (ON setting) or not (OFF setting) as shown in FIG. ) Is set. As a result of this determination, the control unit 60 proceeds to step S34 if the “display on X1 (left end)” setting is ON, and proceeds to step S35 if the setting “display on X1 (left end)” is OFF (step S35). S33).

  The control unit 60 sets the column of the two-dimensional matrix to X1 (left end), and makes a line break for the row of the two-dimensional matrix. This line feed is, for example, an operation of moving to the next line Y2 if the line before the line feed is the Y1 line (step S34).

  The control unit 60 creates a parameter display frame with the column X of the two-dimensional matrix and the row of the two-dimensional matrix Y (step S35).

  The controller 60 increments the two-dimensional matrix column X and the loop counter i (step S36).

  The control unit 60 determines whether or not the loop counter i is greater than the total number of parameters N (here, 9). As a result of this determination, if the loop counter i is smaller than the total number N of parameters, the control unit 60 proceeds to step S32. If the loop counter i is larger than the total number N of parameters, the control unit 60 ends the subroutine and proceeds to step 24 in FIG. 2 (step S37). .

  The operator uses the input unit 10 to measure the measurement conditions (distance D, circumference C, area A), distance measurement D1, D2, D3, circumference measurement C1, C2, C3, area measurement A1, A2 respectively. , Set the measurement points and measurement area of A3. The control unit 60 calculates the distance, perimeter, and area for the set measurement points and measurement areas, and stores them in the storage unit 40 (step 24).

  The control unit 60 reads the calculated values for the distance measurement D1, D2, D3, the perimeter measurement C1, C2, C3, and the area measurement A1, A2, A3 from the storage unit 40, and displays each value in the display area of the display format. (Step 25).

  As described above, according to the ultrasonic diagnostic apparatus of the first embodiment, the operator selects a desired measurement condition from among the plurality of measurement conditions using the input unit 10, and the control unit 50 A display format is generated based on the selected measurement condition, and the display format is displayed in a first display area of the display unit 50 (here, an area juxtaposed below the screen of the display area of the ultrasonic image). By doing so, items related to each other in the measurement result of the ultrasonic image can be regularly displayed. In other words, the control unit generates a display format for displaying a plurality of measurement items obtained from the measurement conditions set by the setting unit, and arranges the plurality of measurement items in the display format and displays the display items. It is displayed on the part. In addition, the control unit has a function of making a line break at an arbitrary measurement item among the plurality of measurement items and arranging it in the display format. The display format is generated by adding line feed switching information (ON) to the desired measurement condition.

  In addition, the first display area may be separated on the top or bottom of the screen as long as it is an area adjacent to the display area of the ultrasonic image.

  In addition, the unique effect of the first embodiment is that the operator can set the condition setting work interactively and efficiently.
