Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a method for automatically obtaining the cardiac cycle video of the ultrasound video of the key section of the fetus, the purpose of which is to intelligently extract the fetal key Cardiac cycle video clips in the section (four-chamber heart, left ventricular outflow tract, right ventricular outflow tract, 3VT section, etc.) The technical problem of occupying hard disk storage resources caused by video data, and the screening of a large number of cardiac cycle videos and interference frames in the video data lead to a huge workload and extremely time-consuming technical problems, as well as the high professional level of sonographers. Technical issues with poor universality

Embodiment Construction

[0038]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0039] The present invention automatically acquires dynamic cycle video clips of the key sections of the fetal heart (four-chamber heart, left ventricular outflow tract, right ventricular outflow tract, three-vessel trachea, etc.) The standardization, minimization and effectiveness of cardiac cycle video data collection saves hard disk resources and provides the most effective and streamlined mat...

Abstract

The invention discloses a method for automatically acquiring a fetal key section ultrasonic video center dynamic period video, which specifically comprises the following steps of: firstly, positioninga heart part which is continuously deformed by using a target tracking technology, and then primarily identifying diastolic and systolic end stages by using a classification method, so as to obtain arough heart period boundary frame; and finally, using a cross gating bilinear matching model for checking and finely positioning a fragment matched with the standard video in the long video, so thata complete cardiac cycle video under a related standard section can be more accurately matched from two aspects of obvious boundary frames in the cardiac cycle video and dynamic matching in the middle. The invention aims to intelligently and automatically intercept a fetal cardiac cycle video from an ultrasonic video by using deep learning, and provide the most direct and effective basis for subsequent intelligent diagnosis.

Description

technical field [0001] The invention belongs to the technical field of prenatal ultrasonic examination, and in particular relates to a method for automatically obtaining the cardiac cycle video of the ultrasonic video of the key section of the fetus. Background technique [0002] Currently, fetal echocardiography is the most important means of screening for congenital heart disease in the second trimester of pregnancy. Based on the results of fetal heart ultrasound examination, it can reduce the birth of many fetuses with serious and complicated abnormalities. At the same time, for fetuses with mild cardiac abnormalities in the examination results, if the prenatal diagnosis and necessary safeguard measures can be made, the newborn's heart rate will be improved. Abnormalities can be treated in time. [0003] During the ultrasound examination of the fetal heart, the cardiac cycle video obtained from the fetal key views (including four-chamber heart, left ventricular outflow t...
