Ultrasonic diagnosis device, ultrasonic image analysis device, and ultrasonic image analysis method

Abstract

The present invention provides an ultrasonic diagnosis device, an ultrasonic image analysis device and a method thereof. A motion parameter measuring unit (9) two-dimensionally measures a motion parameter of a myocardial tissue by a tracking process on time-series ultrasonic image data acquired by transmission and reception of ultrasonic waves to and from a sample. On the other hand, a time phasesetting unit (8) adds a diastolic heartbeat time phase, which is set on the basis of a systole end specified by a time phase where a cardiac cavity area of the ultrasonic image data is the smallest and a diastole end specified by an R wave in an electrocardiographic waveform of the sample, relative to the systole end to time-series parameter image data generated by a parameter image data generating unit (10) on the basis of the motion parameter. An image data extracting unit (11) extracts parameter image data to which the diastolic heartbeat time phase closest to a desired diastolic heartbeattime phase set by an input unit (13) is added and displays the extracted parameter image data on a display unit (12).

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus, an ultrasonic image analysis apparatus, and an ultrasonic image analysis method, and particularly to an ultrasonic diagnostic apparatus capable of generating and displaying parametric image data based on motion parameters such as cardiac muscle by analyzing ultrasonic image data collected from a subject, An ultrasonic image analysis device and an ultrasonic image analysis method. Background technique [0002] Ultrasonic diagnostic equipment emits ultrasonic pulses generated from the vibrating element built in the ultrasonic probe into the subject, and uses the vibrating element to receive ultrasonic reflected waves generated due to differences in the acoustic impedance of the subject's tissues and display them on the monitor. superior. This diagnostic method can easily observe real-time two-dimensional image data by simply touching the ultrasonic probe to the body surface, so it is w...

AI Technical Summary

Problems solved by technology

[0009] In the case of selectively observing the parametric image data in the predetermined time period of the early diastole, it is difficult to accurately observe the myocardial tissue in the predetermined time period from the parametric image data continuously displayed as moving images conventionally. "skew" etc.

In addition, in order to accurately set the predetermined time period, it is necessary to use the end-systolic phase of myocardial tissue as a reference, and the method based on the end-diastolic phase determined by the timing of the R wave of the electrocardiographic waveform as in the past cannot be accurately set.
