Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ultrasonic diagnostic apparatus, and particularly to an ultrasonic diagnostic apparatus with a cine loop function capable of storing biological data of a living body.

[Prior Art] In the medical field of the heart, circulatory system, and the like, ultrasonic diagnostic devices have conventionally been used to observe tissues and organs inside a living body. This ultrasonic diagnostic device uses, for example, a B-mode system that displays tomographic images of the heart on a CRT monitor in real time, an M-mode system that displays the movement of each part inside the body, and a system that displays blood flow information within the body. A D-mode display method is adopted. It is also common practice to display an electrocardiogram waveform on a monitor as a biological signal.

On the other hand, devices equipped with a cinerama memory (hereinafter referred to as cine memory) are also provided. This cine memory stores, when a diagnostic image is frozen, tomographic image data within a predetermined period near the freeze timing, or biological signals for the same period together with this. Therefore, by reading and reproducing the contents of the cine memory after freezing, it is possible to observe, record, measure and diagnose tomographic images and biological signals before and after the freeze timing.

In ultrasonic diagnostic equipment equipped with such a cine loop function, when playing cine memory, for example, a B button is displayed in the center of the monitor.
The mode image is displayed along with the electrocardiogram waveform, phonocardiogram, pressure pulse wave, etc. at the bottom of the monitor.

[Problem to be solved by the invention]

In the conventional ultrasonic diagnostic apparatus, a diagnostician may perform predetermined calculations by tracing biological information read out from a cine memory onto a monitor. The result of this calculation is temporarily stored in the overlay memory of the DSC.

However, for example, when the screen is scrolled -H in the D mode and another image is read out, information such as the previous trace result, calculation result, or cursor position (hereinafter referred to as trace result, etc.) is erased. I ended up being
The diagnostician cannot view the trace results again. Therefore, in such a case, with the conventional apparatus, the same processing as described above must be performed again, and efficient diagnosis cannot be performed.

An object of the present invention is to provide an ultrasonic diagnostic apparatus that can store trace results, calculation results, etc. processed based on various biological information, and can perform efficient diagnosis.

[Means to solve the problem]

An ultrasonic diagnostic apparatus according to the present invention displays biological data on a monitor by transmitting and receiving ultrasonic waves to and from a living body, and includes a cine memory and an overlay memory.

The cine memory stores biometric data for a predetermined period of time. The overlay memory stores trace results, calculation results, etc. regarding each biological data stored in the cine memory.

[Effect]

In the ultrasonic diagnostic apparatus according to the present invention, the cine memory stores biological data for a predetermined period. When the cine memory is reproduced, the trace results etc. performed by the diagnostician based on each reproduced biological data are stored in the overlay memory. Thereby, each biometric data stored in the cine memory and the trace results etc. stored in the overlay memory can be made to correspond to each other.

Therefore, at the time of diagnosis, each biological data stored in the cine memory and the trace results etc. stored in the overlay memory can be read respectively, which is particularly effective when repeatedly replaying the contents of the cine memory for diagnosis. Diagnosis can be made.

The biocinemory 6 stores biosignal data for a predetermined period while being updated sequentially. The overlay cine memory 7 stores trace results, calculation results, etc. regarding each biological information stored in the image cine memory 5 and the biological cine memory 6. The overlay cine memory 7 is composed of the same number of planes as the image cine memory 5 and the bio cine memory 6, and stores trace results based on each biological data stored in each plane of the image cine memory 5 and the bio cine memory 6. It can be stored in the corresponding plane. The respective outputs of the cine memories 5, 6.7 constituting the memory section 8 are input to the DSC 3, respectively.
