COMPUTERIZED SCHEME FOR DISTINCTION BETWEEN BENIGN AND MALIGNANT NODULES IN THORACIC LOW-DOSE CT

摘要

A system, method, and computer program product for classifying a target structure in an image into abnormality types. The system has a scanning mechanism that scans a local window across sub-regions of the target structure by moving the local window across the image to obtain sub-region pixel sets (fig. 2b element 200). A mechanism inputs the sub-region pixel sets into a classifier (fig. 2b element 210) to provide output pixel values based on the sub-region pixel sets, each output pixel abnormality, the output pixel values collectively determining a likelihood distribution output image map. A mechanism scores the likelihood distribution map to classify the target structure into abnormality types (fig. 2b element 220). The classifier cab be, e.g. , a single-output or multiple-output massive trainin artifical neural network MTANN .
