Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electrocardiogram (ECG) in an ultrasonic diagnostic apparatus.
This invention relates to a display device K for biological signals such as a phonocardiogram (PCG).

[Prior art to the invention]

In an ultrasound diagnostic device, ECG along with ultrasound echo images
When biological signals such as and PCG were displayed in a scroll display or in a compound display, these images and the biological signal (No. 1) overlapped, making it very difficult to see.

Note that scroll display means that the ECCG, etc. is always displayed from right to left (
A paging display is a display in which the image of the ECG, etc. starts from the right edge, and when it reaches the left edge, the image is erased and the display starts again from the right edge. A format is one in which a plurality of independent images are displayed simultaneously, and a compound is one in which a plurality of cross-sectional images, etc. are combined and displayed as one image.

[Purpose of the invention]

The present invention corresponds to the display position of the ultrasound echo image.

The aim is to overcome the difficulty of viewing biological signals by moving the display position of the biological signals.

[Key points of the invention]

The present invention detects the display position of an ultrasound echo image and the display position of a biological signal, and moves the display position so that the display position of the biological signal overlaps with the display position of the ultrasound echo image. It is.

[Embodiments of the invention]

An example will be described below in which ultrasonic echo images are simultaneously obtained from two probes at different frequencies, and the two are combined to display a wide-field image.

In FIG. 1(a), the glove 1.2 is fixed to the arm 3 and sends mutual position detection signals to the image control unit 4 together with ultrasound echo signals. The image control unit 4 has both probes 1
．． 51.5 images obtained from each glove depending on the relative position of 2
2 are combined and displayed on the display section 5.

On the other hand, biological signals from the living body are detected by the detection unit 6. After passing through the biological signal display control unit 7, it is displayed as a waveform diagram 53, for example. The display position of the biosignal 53 is set at a standard position, and is set at a relatively central position as shown in FIG. 1(b) assuming that the composite image is relatively small.

1-However, when the overlap detection control unit 8 detects that the composite image overlaps with the standard position as a result of moving one of the probes, the biosignal display control unit 7 shifts the display position of the biosignal, The movement is continued until the overlap detection control section 8 detects no overlap. As a result, when the composite image is relatively spread out as shown in Figure 1), the biosignal moves to the upper right corner.

In addition, when the display position is fixed as in the multi-format, for example, as shown in Figure 2, the biological signals can be displayed in single sector image mode (b) and in dual sector image mode (a). The display position may also be changed.

〔Effect of the invention〕

According to the present invention, it is possible to prevent the ultrasonic echo image and the biological signal display from overlapping each other, so that it is possible to display a lot of information in an easy-to-read manner.
