Abstract
We report on work undertaken as part of the SAMMIE project (AIM project A2032) on the development of advanced segmentation aids for object demarcation in MR and CT images. Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) are two very differing methods for producing three-dimensional radiological image data sets. Our work concentrates on a set of tools produced to help clinicians in producing object outlines in three dimensional image sets of the human brain. The methods used include thresholding, digital morphological operators and active contour models. These methods are accessed from within a suite of programs that help the clinician (or rdaiologist) manage information about medical image data sets. Other tools include two and three dimensional idealised atlases of the brain. Here we describe a multiple energy active contour and a related profile-based segmentation operator. 1 Introduction Active contour models (or snakes) first developed by Kass et al (1) are a patter...
