Abstract
The most prominent difference between an immature skeleton and a mature adult skeletal system is the presence of a Physis which is also known as the growth plate. In this paper a methodological approach based on 3D level set is proposed for fully automated segmentation of Growth plate in Radius bone. The implemented algorithm consists of several stages for a successful segmentation. In the first step, Radius bone is extracted using 3D active contour method. After extracting the Radius bone, to obtain the growth plates the ROI should be extracted according to anatomical information and bone shape. The main challenge in segmenting the growth plates occurs when these plates get closed and narrowed due to aging. For enhancing the contrast in this step, a Gabor filter is used, and finally using sphere spaces as the primary mask of level-set algorithm, a 3D segmentation of Radius Growth plate can be performed. We utilize the proposed approach as part of a computer-aided diagnosis system for robust legal age determination...
