A method for intelligent acquisition of fetal cardiac cycle images based on ultrasound four-chamber view

Abstract

The invention discloses a method for obtaining fetal cardiac cycle images intelligently based on ultrasonic four-chamber views. The method includes the steps that a ultrasonic cardiac video containingthe fetal four-chamber views with a plurality of cycles is collected in real time; the four-chamber heart views in ultrasonic cardiac video frames identified by a trained YOLO v3 model based on single-frame image target detection are used for assisting a sonographer in determining a standard view, and an SVM is used for distinguishing end-systole frames; next, front and rear frames of the preliminarily positioned end-systole frames are input in a GRU module for further optimization selection, and then more accurate and reasonable frames corresponding to end-systoles of the four-chamber viewsare obtained; and in this way, all frames of every two adjacent end-systoles and the intermediate end-systole are a cardiac cycle, and even extraction of the four to five frames is final output. The method aims at using computers to automatically intercept fetal ultrasonic cardiac cycles to facilitate subsequent automatic auxiliary diagnosis.

Description

technical field [0001] The invention belongs to the technical field of computer-aided diagnosis, and more specifically relates to a method for intelligently acquiring fetal cardiac cycle images based on an ultrasonic four-chamber view. Background technique [0002] Early screening of fetal heart disease can greatly improve the health rate of newborn babies, and is also conducive to the timely treatment of heart disease. Echocardiography is widely used for early screening of fetal heart disease because of its low price, strong real-time performance, and no harmful radiation. At present, the widely used echocardiography is three-dimensional and four-dimensional ultrasound. Although they are relatively intuitive, they rely on two-dimensional ultrasound images. Therefore, two-dimensional ultrasound images are the basic basis for the diagnosis of the fetus. image derived.

Problems solved by technology

[0003] However, there are some unavoidable technical problems in cardiac ultrasound technology based on two-dimensional ultrasound images: first, the complexity and professionalism of its operation determine that two-dimensional ultrasound images must be interpreted by professional sonographers who have received strict study and training for Second, different doctors will have different diagnostic results for the same subject's heart-related indicators obtained by existing echocardiography techniques, and even the same doctor's diagnostic results for the same subject There will also be differences before and after, which will greatly affect the accuracy of the final diagnostic result
