Purpose
The Radius and Ulna bones, both with carpus, grow as a unit, and normal growth depends upon a synchronization of the growth of these bones. Statistical models of shape are a promising approach for robust and automatic segmentation of medical image data. This work describes the construction of a statistical shape model of the Radius and Ulna bones. For 3D model-based approaches, however, building the 3D shape model from a training data set of segmented instances of an object is a major challenge and currently remains an open problem. In this study, we propose an active contour image segmentation method, then we create 3D statistical shape model of Radius and Ulna bones for MRI datasets. In the future works we utilize the proposed approach as part of a computer aided diagnosis system for legal age estimation...
