Transparent band boundary determination method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a zona pellucida boundary determination method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a to-be-detected embryo image, and determining an embryo mass center position of the embryo image; based on the embryo mass center position and a pre-estimated radius of a zona pellucida in a preset embryo image, determining a pre-estimated circular ring region where the zona pellucida in the embryo image is located; performing edge detection on the estimated circular ring region to generate an edge detection image; and respectively performing fitting operation on the outer boundary edge range and the inner boundary edge range of the transparent band in the edge detection image, and determining inner boundary information and outer boundary information of the transparent band based on a fitting result. According to the technical scheme, resources can be saved, and the determination precision of the anatomical position can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of intelligent medical technology, and in particular to a method, device, electronic equipment and storage medium for determining the boundary of the transparent zone. Background technique [0002] Embryo biopsy is an important step before the invasive examination, which can help the invasive examination of embryo implantation to select high-quality startled embryos, thereby significantly improving the success rate of IVF. During this procedure, a portion of the zona pellucida (ZP) enclosing the blastomeres is dissected and one or two blastomeres are extracted from the embryo, as improper dissection points can result in lysis of the embryo. Therefore, how to determine the boundary of the zona pellucida to determine the position of dissection becomes an important factor in determining the success rate of invasive examination. [0003] In the prior art, embryologists are usually required to ma...

AI Technical Summary

Problems solved by technology

However, the contrast between the blastomere and the zona pellucida in the embryo image is poor, and embryologists are prone to errors in determining the anatomical position by human eyes, which leads to the failure of invasive inspection operations; moreover, it is very difficult to manually determine the anatomical position Consuming energy and human resources, the accuracy of the determined anatomical position is poor
