Embodiment Construction
[0012] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present invention clearer, the following further describes the present invention in detail with reference to embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0013] The embodiment of the present invention provides a method for automatically segmenting breast tumors based on three-dimensional MRI images, which includes the following steps:
[0014] S01. Image preprocessing: provide an initial MRI image, and preprocess the initial MRI image using a non-local average filter;
[0015] S02. Breast tumor location: build a multi-layer processing model on the training set, use convolutional neural network to abstract the features of the training object, automatically extract segmentation features, and output the probability distribution map of tumor location;...
