Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an M-mode ultrasonic diagnostic apparatus.

In general, ultrasound diagnostic equipment attempts to diagnose the internal tissue structure of the human body by transmitting ultrasonic waves from an ultrasonic transducer called a probe into the human body and analyzing the reflected waves from various parts inside the human body. Among them, the M-mode ultrasound diagnostic device is designed to display temporal changes in each part of the human body, that is, the state of movement of each part, with the vertical axis representing the depth from the surface of the human body and the horizontal axis representing time. This is especially used for the detection of echocardiograms.

However, the conventional M-mode ultrasonic diagnostic apparatus has only one system of M-mode echocardiogram detection circuit, and only one M-mode echocardiogram can be viewed.

This invention was made in view of the above-mentioned drawbacks of the conventional ones, and is an M-mode ultrasonic diagnostic device that is equipped with multiple probes and multiple M-mode echocardiogram detection circuits to emit beams in multiple directions. To provide an M-mode ultrasonic diagnostic device that can perform simultaneous observation to obtain a lot of information at the same time, and can also understand the time phase relationship of the plurality of M-mode echocardiograms to improve diagnostic accuracy. The purpose is to

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of an M-mode ultrasonic diagnostic apparatus according to an embodiment of the present invention.
41 is an M-mode echocardiogram detection circuit that detects an M-mode echocardiogram from the reflected wave from the human body received by the probe fil (21), and +51 is the time on the horizontal axis that detects the M-mode echocardiogram from the above-mentioned two M-mode echocardiograms. This is a display device that displays the axes at the same time.

FIG. 2 shows a cross-section of a human heart diagnosed by the M-mode ultrasound diagnostic device, and in the figure, ACW is the chest wall, ATT, li, tricuspid valve, I V S, ventricular septum,
LV is the left ventricle, AML is the anterior mitral valve, PML is the posterior leaflet of the mitral valve, LA is the left atrium, RA is the right atrium, RV is the right ventricle, LV
PW is the left ventricular posterior wall, AV is the aortic valve, and AD is the aorta. Also, A is the first beam from the first probe (1), which is used to measure the part that needs to be constantly seen, for example, the mitral valve in this case.B is the second beam from the first probe (1). This is the second beam from the feeler (2), and is used to measure the location that is desired to be viewed on a case-by-case basis depending on the patient's symptoms, for example, in this case, the diameter of the aorta.

Further, FIG. 3 shows an M-mode core 1-cor diagram obtained by measurement with this device. Figure (a) is an M-mode echocardiogram obtained by the first beam A, where ACWt and ACW2 are the outer and inner walls of IjJ&i, respectively, and IVS+ and l
VS2 are the outer and inner walls of the interventricular septum, AM
L indicates the anterior mitral valve, LVPWl; T, VPV & indicates the movement of the outer and inner walls of the left ventricular posterior wall, respectively. Figure (b) shows an M-mode echocardiogram using the second beam B. In addition to the same images as in Figure (a), AVl is the aortic valve on the upper side of Figure 2, and AV2 is on the lower side of Figure 2. Showing the movement of the aortic valve. In addition, FIG. 3C shows an electrocardiogram, and R in the figure is a wave of the electrocardiogram waveform.

According to this device, a lot of information can be obtained by using the first beam A for diagnosing the left ventricle including the mitral valve and the second beam B for diagnosing the aortic valve. Since the A and H echoes can be observed while maintaining their time phase relationship, the accuracy of diagnosis can be greatly improved.

In the above embodiment, two probes and two M-mode echocardiogram detection circuits are provided, but a larger number may be provided.

As described above, according to the present invention, the M-mode ultrasound diagnostic apparatus is provided with a plurality of probes and a plurality of M-mode echocardiogram detection circuits, so that echocardiography using ultrasound beams in multiple directions is possible. Diagrams can be observed while maintaining the correct time phase relationship with each other, and a large amount of information can be obtained, which has the effect of greatly improving the accuracy of diagnosis.
