91. Boundary tracking in 3-D binary images to produce rhombic faces for a dodecahedral model

Abstract

A study was conducted to analyze an algorithm used to track boundaries in three-dimensional binary images based on rhombic dodecahedral voxels. The algorithm supports a list of all the rhombic voxel faces in the boundary. connectivity of bels for cubic voxels where determined. The notion of a boundary for rhombic dodecahedral voxels were determined from the cubic voxels. Results indicated the effectiveness of the algorithm for generation a list of all rhombic faces of a boundary in three-dimensional binary images.

94. A Bayesian approach to PET reconstruction using image-modeling Gibb priors: implementation and comparison

Abstract

We demonstrate that (i) classical methods of image reconstruction from projections can be improved upon by considering the output of such a method as a distorted version of the original image and applying a Bayesian approach to estimate from it the original image (based on a model of distortion and on a Gibbs distribution as the prior) and (ii) by selecting an 'image-modeling' prior distribution (i.e., one which is such that it is likely that a random sample from it shares important characteristics of the images of the application area) one can improve over another Gibbs prior formulated using only pairwise interactions. We illustrate our approach using simulated Positron Emission Tomography (PET) data from realistic brain phantoms. Since algorithm performance ultimately depends on the diagnostic task being performed. we examine a number of different medically relevant figures of merit to give a fair comparison. Based on a training-and-testing evaluation strategy, we demonstrate that statistically significant improvements can be obtained using the proposed approach. We also present a statistical verification of the normality condition required for the above statistical claim.
