Claim 4:
5. The method as claimed in claim 1, wherein for each preset lesion type, calculating the fusion feature map corresponding to each preset lesion type according to the first feature map and the weight value corresponding to each preset lesion type comprises:
for each preset lesion type, putting the first feature map and the weight value corresponding to each preset lesion type into a preset weighted sum formula to calculate the fusion feature map corresponding to each preset lesion type;
wherein the weighted sum formula is:, F
      c
    
    =
    
      
        ∑
        
          k
