Embodiment Construction
[0043] The present invention will be further described below in conjunction with the accompanying drawings.
[0044] refer to Figure 1-Figure 5 , a neurofibroma segmentation method combined with spatial guidance, comprising the following steps:
[0045] Step 1, this step is based on the data set analysis strategy of nnU-Net, and performs data preprocessing on training sample images and labels, including cropping, data set analysis, resampling and normalization;
[0046] Step 2. Construct a network instance based on the network hyperparameters obtained from the data set analysis in the first step, using nnU-Net as the backbone network and adding a spatial guide branch (Spatial Guide Branch);
[0047] Step 3, Patch-based Training, the training label generates spatial guidance to simulate user interaction information, and the spatial guidance is randomly set to zero, so that the network can not only learn to respond to guidance information, but also automatically segment withou...
