Multi-component semantic segmentation method based on four-cavity heart tangent plane of multi-disease fetus

Abstract

The invention discloses a multi-component semantic segmentation method based on a four-cavity cardiac tangent plane of a multi-disease fetus. The method comprises the steps of collecting an ultrasoniccardiac sequence image, copying and expanding the sample size of the collected multi-position ultrasonic cardiac sequence image, and segmenting the sample size; segmenting the plurality of componentsbased on the four-cavity heart tangent planes of the plurality of disease types; using a proportion balance strategy to obtain a better segmentation effect, especially in a group with a low data volume proportion. The method is the first method for achieving segmentation of multiple core components in the ultrasound cardiogram of the fetus with multiple diseases, greatly assists doctors in statistical analysis of multiple key indexes of the heart of the fetus, and is beneficial to remote medical treatment, especially to improvement of the medical level of grassroots remote areas.

Description

technical field [0001] The invention relates to a multi-component semantic segmentation method based on a multi-disease fetal four-chamber view. Background technique [0002] In clinical practice, ultrasonography is an important part of prenatal examination, which can provide reliable and clear information, provide scientific consultation services for pregnant women, and give appropriate postpartum guidance strategies. [0003] However, at present, more studies are based on adult echocardiography, and research on the left atrial LV; although some studies have shown that the segmentation of the adult LV and the segmentation based on the four-chamber view have been used. Left atrium LV segmentation is performed on the four-chamber images of end-systolic ES and end-diastole ED; however, there is still no solution for multi-disease multi-component segmentation, and there is no multi-component segmentation method for multi-disease fetal four-chamber view.
