【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. However, this does not limit the present invention. FIG. 1 is a block diagram of an essential part of an embodiment of a parameter setting device for an image diagnostic apparatus according to the present invention. The parameter setting device 1 of this image diagnostic device includes a biological signal waveform sensor group 2, a PSC (pulse sequence controller) 3, a PDC (plasma display controller) 4, a plasma display 5, a touch panel 6 and a DMP (display management processor). It is composed of 7.

The touch panel 6 is installed on the front surface of the screen of the plasma display 5, and is used to set parameter values such as imaging conditions.

The PDC 4 displays a screen G as shown in FIG. 2 on the plasma display 5. In this screen G, two waveform display areas H1 and H2 are areas for displaying a biological signal waveform such as an ECG waveform or a pulse waveform. The waveform display buttons K1a, K1b, ..., K2a, K2b, ... Are displays for indicating a touch area for performing an operation related to the display of the biological signal waveform. The value input button group L is a display for showing a touch area for designating a numerical value or a position.

To display a desired biological signal waveform in the waveform display area H1, the user first touches the area of the touch panel 6 corresponding to the WV1 button K1a. Then, the touched position information is transmitted to the DMP 7 via the PDC 4.

The DMP 7 notifies the PSC 3 that it is requested to display the biological signal waveform in the waveform display area H1 based on the transmitted position information.

Next, the user selects a waveform display button of a desired biological signal waveform from the waveform display buttons K1b, K1c, ... Such as the ECG button K1b, and displays it on the area of the touch panel 6 corresponding to the waveform display button. touch. Then, the touched position information is transmitted to the DMP 7 via the PDC 4. The DMP 7 determines the biological signal waveform to be displayed from the transmitted position information. Then, the information of the confirmed biological signal waveform is transmitted to the PSC 3. The PSC 3 selects a biosignal waveform sensor corresponding to the biosignal waveform information from the biosignal waveform sensor group 2. Then, the waveform data is collected from the selected biological signal waveform sensor and transmitted to the PDC 4.

Thus, the PDC 4 displays the biological signal waveform in the waveform display area H1 of the display screen G of the plasma display 5 based on the waveform data. Incidentally. In the waveform display area H2, the biological signal waveform is displayed by the same operation.

An exemplary diagram of the biological signal waveform is shown in FIG. The waveform display area H1 has 300 dots in the horizontal direction and 128 dots in the vertical direction. The displayed speed is about 100 dots per second. When new waveform data comes in after the waveform data has been displayed for 300 dots in the horizontal direction, the oldest waveform data is discarded and all the remaining waveform data are moved by one dot in the horizontal direction. Then, new data is displayed at the position of 300 dots in the horizontal direction. It is also possible to renew the display for each waveform data for 5 dots, for example.

For setting the threshold value, the user inputs the value of the threshold value T using the value input button group L on the display screen G as a percentage of the maximum value of the biological signal waveform. Then, the line cursor T is displayed at a position corresponding to the threshold value T. The user moves the line cursor T by inputting a numerical value from the key of the value input button group L 1 while observing the biological signal waveform, thereby visually observing the relationship between the biological signal waveform and the threshold T, and the value of the threshold T Can be set easily.

When the threshold T is set, the BPM is automatically calculated and displayed from the reciprocal of the interval between the intersections of the biological signal waveform and the threshold T.

FIG. 4 shows an enlarged display of the biological signal waveform. The vertical line segment displayed for each dot in the horizontal direction is a line segment connecting the maximum value and the minimum value of the biomedical signal during the time of 10 ms. When the line segment based on the measured data is displayed on the PDC 4, if the adjacent line segments are completely separated as shown in FIG. 4A, the adjacent line segments are displayed as shown in FIG. 4B. The lines are interpolated and displayed so that the minutes do not separate.
