Abstract

Size and shape analysis is one of the tasks in automated measurement of colon polyps using Computed Tomography Colonography (CTC) images. The research objective was to measure the smaller polyps using image processing techniques. This paper proposes a knowledge-based approach using a semiautomatic method of colon segmentation and morphological image processing methods. The retrospective study included 35 TC scans for evaluation. The combined approach of analyzing he polyp from domain perspective and the skeletonization has iven good results. It takes ~7 minutes for smaller polyp easurement in a CTC scan of 450-500 images using ultithreading on a high-performance computer. The results were tatistically tested at α=5% and the measurements were cceptable
