Ejecting fraction data processing method and device based on cardiac ultrasound video

Abstract

The embodiment of the invention relates to an ejection fraction data processing method and device based on a cardiac ultrasound video. The method comprises the steps that the cardiac ultrasound video is acquired; performing image framing to obtain a first framed image sequence; performing left ventricle lengthwise axis key point identification on each first sub-frame image based on an image target key point identification model; performing left ventricle semantic segmentation processing on each first framing image based on an image semantic segmentation model to generate a second framing image with a left ventricle segmented sub-image; screening processing of framing images at the end of a systolic period and at the end of a diastolic period is carried out on the second framing image sequence; performing left ventricular volume calculation to generate corresponding left ventricular volume parameters; generating a systolic end volume mean value and a diastolic end volume mean value; and ejection fraction data is calculated and generated according to the volume mean value of the end of the systolic period and the end of the diastolic period. By means of the method, the manual intervention link in a traditional method can be eliminated, and the ejection fraction calculation precision and accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for processing ejection fraction data based on cardiac ultrasound video. Background technique [0002] Ejection fraction refers to stroke volume, that is, the percentage of blood ejected from one side of the ventricle in one heartbeat to the end-diastolic volume of the ventricle, and is one of the important indicators for judging the health of the heart. The ejection fraction was calculated as (end-diastolic volume of the ventricles-end-systolic volume of the ventricles) / end-diastolic volume of the ventricles. The traditional measurement method of ejection fraction is that the operator selects the end-diastole and end-systole video framed images from the echocardiography video based on personal experience, and then uses manual methods to perform left ventricular The end-diastolic and end-systolic volumes of the left ventricle were estimated according ...

AI Technical Summary

Problems solved by technology

This method of operation is too dependent on manual experience, not only the screening accuracy of end-diastole and end-systole images cannot be guaranteed, but also the accuracy of endometrial markers cannot be guaranteed, and there will be large errors in the accuracy of the naturally estimated ejection fraction
