摘要：Computed Tomography Colonography (CTC) is the new generation technique for detecting colorectal polyps using volumetric CT data combined with Computer Aided Detection (CAD) system. The aim of this paper is to detail the implementation of a fully integrated CP-Miner system that is able to identify the polyps in the CT data. The CP-Miner system has a multistage implementation whose main system components are: 1. Interpolation, 2. Automatic Colon Segmentation, 3.Feature extraction, 4.Polyp Detection. The proposed system has the aim to reduce the number of false positives than the existing system. The developed system provides 100% sensitivity for polyps greater than 6mm, provides 83.33% sensitivity for polyps within 3 to 6mm, 69.23% sensitivity for polyps less than 3mm. The overall sensitivity of the CP-Miner system is 84.18%.
