Embodiment Construction
[0047] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] figure 1 It is the low image contrast and fuzzy mode brain tumor segmentation provided by the embodiment of the present invention. The 4 columns on the left are the input images of the MRI data, and the fifth column is the corresponding real calibration results. The green, yellow, and red areas highlight the WholeTumor (WT), Tumor Core (TC), and Enhancing Tumor (ET) sections, respectively.
[0049] figure 2 is the method framework of the present invention. Infer results from modalities using a cascaded structure. E and D represent the encoder and decoder in 3D U-Net, respectively, and C is the environment mining module of the described method.
[0050] Such as figure 2 Shown is a multi-level structure network for segmenting brain tumor reg...
