Title:
METHOD AND DEVICE FOR MARKING LUNG AREA SHADOWS IN MEDICAL IMAGE, SERVER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/073120
Kind Code:
A1
Abstract:
A method and a device for marking lung area shadows in a medical image, a server and a storage medium, the method comprising: performing lung area segmentation on a medical image containing lungs according to a pre-trained lung area division model to obtain a lung area image; detecting preset key feature points contained in the lung area image according to a pre-trained lung key feature point detection model; and partitioning the lung area image on the basis of the preset key feature points contained in the lung area image and marking shadows contained in partitioned lung areas.
