Published:24 June 2017Publication History

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 semi-automatic method of colon segmentation and morphological image processing methods. The retrospective study included 35 CTC scans for evaluation. The combined approach of analyzing the polyp from domain perspective and the skeletonization has given good results. It takes ~7 minutes for smaller polyp measurement in a CTC scan of 450-500 images using multithreading on a high-performance computer. The results were statistically tested at α=5% and the measurements were acceptable.
