Embodiment 1
[0045] The fatty liver intelligent grading evaluation method and system based on abdominal CT in one embodiment of the present invention specifically includes the following steps:
[0046] Step 1, for example figure 2The preprocessing of the patient’s abdominal CT image data is as follows: use the SimpleITK toolkit to read the DCM image file, use the Numpy toolkit to convert the file into an array matrix, and use the window width and window level technology to correct the CT value of the slice, the window width value is 400hu, The window level value is 100hu, and the bilinear interpolation technology is used to adjust the size of the CT slice. The adjusted slice size is 256*256, and the image connected area method is used to eliminate the equipment background interference information in the image;
[0047] Step 2. Input the CT slice image, use the U-Net segmentation model to segment the CT slice of the patient, output the respective mask maps of the liver tissue and spleen ti...
