[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0036] In this example, see figure 1 and figure 2 As shown, the present invention proposes an automatic head and neck tumor segmentation method in an MRI image, comprising steps:
[0037] S100, training a neural network model based on U-net: the neural network model includes a contraction encoder for analyzing input MRI images and an extended decoder for generating label map output; using skip connections in the U-net architecture will shallow The appearance feature representation of the encoding layer is combined with the high-level feature representation of the depth decoding layer;
[0038] Train the neural network model based on U-net, comprising steps:
[0039] S101, performing data preprocessing and data enhancement on the image training set; data enhancement is t...
