The ultrasonic probe 101 transmits the signal generated by the transmission unit 102 to the subject as an ultrasonic wave, and receives the reflected ultrasonic wave. The receiving unit 103 detects the ultrasonic wave received by the ultrasonic probe 101 as a reception signal. The reproduction unit 104 reproduces the reception signal detected by the reception unit 103 as an ultrasonic image. The control unit 106 controls the transmission unit 102, the reception unit 103, the reproduction unit 104, and the display unit 105. The operation unit 107 transmits an input from an operator for measuring the diagnostic image displayed on the display unit 105 to the control unit 106. The time counter 110 always measures the current time. The calculation formula recording unit 111 records a calculation formula for calculating information set by the operation unit 107 as a measurement result in the calculation unit 108. The recording unit 109 records the measurement result set by the operation unit 107 and simultaneously records the measurement time from the time counter 110. The calculation unit 108 manages measurement results and measurement times. The display unit 105 displays the ultrasonic image of the subject reproduced by the reproduction unit 104, and further displays the measurement result and measurement time from the calculation unit 108.
[0016]
The operation of the ultrasonic diagnostic apparatus configured as described above will be described with reference to FIG. First, the time counter 110 always calculates the current time. In order to make a diagnosis for the subject, an ultrasonic wave is transmitted from the transmission unit 102, and the ultrasonic wave is transmitted / received to / from the subject via the ultrasonic probe 101. A signal received from the ultrasound probe 101 is received via the receiving unit 103, reproduced by the reproducing unit 104, and displayed on the display unit 105 (step 1). The operator operates the operation unit 107 with respect to the diagnostic image reproduced in the reproduction unit 104, and sends the operation content to the control unit. (In the case of a measurement operation, the control unit 106 sends measurement information to the calculation unit 108. The calculation unit 108 inputs a calculation formula from the calculation formula recording unit 111 based on the measurement information sent from the control unit 106, and The calculation is performed and the measurement result is calculated (step 2) The calculation unit 108 records the measurement result in the recording unit 109, and simultaneously inputs the measurement time from the time counter 110, and associates the measurement result with the recording unit 109. (Step 3) Steps 2 and 3 are repeated as many times as necessary (Step 4) After the measurement, the measurement result and the measurement time are input from the recording unit 109 to the calculation unit 108, and the calculation unit 108 Converts the measurement result and measurement time into list display information and inputs it to the display unit 105. The list display information is displayed on the display unit 105 (step 5). That shows the management screen. Management screen 200 is to list the results and the measurement time measurement.
[0017]
As described above, according to the first embodiment of the present invention, the measurement time is stored together with the measurement result at the time of measurement, and the measurement result and the measurement time are managed. It is possible to determine whether measurement results are mixed.
[0018]
FIG. 4 shows a block diagram of a second embodiment of the ultrasonic diagnostic apparatus of the present invention. In FIG. 4, the measurement result erasing operation unit 112 selects an erasing time to be erased by the operator. The erasure calculation unit 113 inputs the current time from the time counter 110, compares the erasure time selected by the operator with the measurement result erasure operation unit 112 with the measurement time stored in the recording unit 109, and records the measurement recorded before the erasure time. The result and the measurement time are deleted from the recording unit 109.
[0019]
The operation of the ultrasonic diagnostic apparatus configured as described above will be described with reference to FIG. First, a list of measurement results and measurement times is displayed in the procedure from step 1 to step 5 of the first embodiment. When the operator performs the erasure process, the operation unit 107 is operated to select the erasure process. If the erasing process is not performed, the process is terminated (step 6). The measurement result erasing operation unit 112 is operated to input an erasing time (step 7). The inputted erase time is sent to the erase operation unit 113. The measurement times stored in the recording unit 109 are compared. The measurement result corresponding to the measurement time before the erasure time is erased (step 8). FIG. 6 shows the management screen displayed in step 8. On the management screen 200, a list of measurement results and measurement times is displayed, and an erase time 201 is displayed.
[0020]
As described above, according to the second embodiment of the present invention, the measurement result and the measurement time are managed, and the measurement result before the erasure time set by the operator is erased. It becomes possible.
[0021]
The erasure time interval is recorded in the recording unit 109 in advance, and the erasure calculation unit 113 calculates the difference (that is, the measurement time interval) from the previous measurement time for each measurement time stored in the recording unit 109. Each calculation is performed to compare the interval between the measurement times with the erasure time interval. When the measurement time interval is larger than the erasure time interval, the previous measurement time of the measurement time may be set as the erasure time. FIG. 7 shows that the recording unit 109 records the difference between the previous measurement time (that is, the measurement time interval) together with the measurement time and the measurement result. In this case, it becomes possible for the operator to set the erase time without operating the erase time.
[0022]
The erasure time interval is recorded in the recording unit 109 in advance, and the erasure calculation unit 113 calculates the difference (that is, the measurement time interval) from the previous measurement time for each measurement time stored in the recording unit 109. Each calculation is performed to compare the interval between the measurement times with the erasure time interval, and when the measurement time interval is larger than the erasure time interval, the measurement result at the previous measurement time of the measurement time may be erased. In this case, the operator can erase the measurement results of different subjects without performing the erasing operation from step 6 to step 8.
[0023]
The function of the ultrasonic diagnostic apparatus according to the present invention can be recorded as a program on a recording medium such as a magnetic disk, a magneto-optical disk, an IC card, a PD, a DVD-RAM, a DVD-ROM, a ROM, and a RAM. Therefore, the function of the ultrasonic diagnostic apparatus according to the present invention can be realized by reading this recording medium with a computer.
