Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A computer program product comprising a non-transitory computer readable medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:
generate, by a candidate generator, a set of candidate three-dimensional image patches from an input volume;
classify, by a candidate classifier, the set of candidate three-dimensional image patches as containing or not containing disease, wherein classifying the set of candidate three-dimensional image patches comprises:
generating an attention mask for each given candidate three-dimensional image patch within the set of candidate three-dimensional image patches to form a set of attention masks;
applying the set of attention masks to the set of candidate three-dimensional image patches to form a set of masked image patches; and
classifying the set of masked image patches as containing or not containing the disease,

wherein the candidate classifier applies soft attention and hard attention to the three-dimensional image patches such that distinctive image regions are highlighted proportionally to their contribution to classification while completely removing image regions that may cause confusion, wherein generating the set of candidate three-dimensional image patches comprises decomposing the input volume into a set of image slabs and applying a first neural network to the set of image slabs to segment the set of image slabs into the set of candidate three-dimensional image patches.
