Embodiment Construction
[0029] The radiomics-based visualization and quantification method for gene heterogeneity in glioma of the present invention will be further described below with a specific example of IDH1.
[0030] Step 1 is image segmentation. The network structure adopted in the present invention is as figure 1 As shown, the downsampling path and the upsampling path are combined in series with the feature maps of the corresponding resolution levels. The downsampling path has three blocks and two convolutional layers. Each block consists of two consecutive convolutional layers with a filter size of 3×3×3 and a max-pooling layer with a stride of 2×2×2. At the end of the downsampling path, two successive convolutional layers are added with a filter size of 3×3×3. Then there is the upsampling path, which also has three blocks. Each block contains a deconvolutional layer with a filter size of 2×2×2, cascaded processing and two consecutive convolutional layers with a filter size of 3×3×3. At ...
