Medical image analysis of 3D CT images based on extension of Haralick texture features

Purpose: A new approach to the segmentation of 3D CT images is proposed in an attempt to provide texture-based segmentation of organs or disease diagnosis. 3D extension of Haralick texture features was studied calculating co-occurrences of all voxels in a small cubic region around the voxel. Results: For verification, the proposed method was tested on a set of abdominal 3D volumes of patients. Statistically, the improvement in segmentation was significant for most of the organs considered herein. Conclusions: The proposed method has potential application in medical image segmentation, including diagnosis of diseases. (C) 2008 Elsevier Ltd. All rights reserved.
