Claim 3:
4. The method according to claim 3, wherein performing the segmentation process on the CT images of the pancreas and the mass to obtain the segmentation mask of the pancreas and the mass of the patient includes:
feeding the 4D input X into a segmentation network trained on an input Y which is one-hot encoded by combining a pancreas dataset with masses of radiologist-segmented pancreatic ductal adenocarcinoma (PDAC) and radiologist-segmented non-PDAC, to obtain the segmentation mask of the pancreas;
wherein Y∈RK×W×H×D, K is a task label indicating a task including a classification task between the masses of the PDAC and the non-PDAC, and a treatment recommendation task, the segmentation network includes an nnUNet as a backbone network and a pixel-level segmentation loss function Lseg,, L
