MEDICAL IMAGE SEGMENTATION METHOD, MEDICAL IMAGE SEGMENTATION APPARATUS AND TERMINAL DEVICE

摘要

Provided is a medical image segmentation method. The method comprises: acquiring a medical image to be detected; inputting said medical image into a trained segmentation model, wherein the segmentation model comprises an encoder and a decoder, the encoder comprises a plurality of first hierarchical structures, the plurality of first hierarchical structures comprise a first input layer, at least one first intermediate layer and a first output layer, the decoder comprises a second input layer, at least one second intermediate layer and a second output layer, and the input of any second intermediate layer comprises a fusion result of the output of the previous layer of the second intermediate layer and the output of at least two first hierarchical structures; and processing said medical image by means of the segmentation model so as to obtain an output result of the segmentation model, wherein the output result comprises a segmentation result regarding a medical feature region in said medical image. By means of the method, the accuracy of image segmentation of a medical image can be improved.
