Statistical shape analysis has become of increasing interest to the neuroimaging community due to its potential to precisely locate morphological changes and thus potentially discriminate between healthy and pathological structures. This paper describes a combined boundary and medial shape analysis based on two different shape descriptions applied to a study of the hippocampus shape abnormaliti...

The human heart is a fragile and dynamic organ that requires careful approach during catheter intervention. It essential for physicians to have high degree of awareness the anatomy relative pose when operating inside heart. One key aspects can aid such interventions knowledge heart’s motion profile. Accordingly, this work addresses objective estimating local predominantly one-dimensional motion...

An improvement of the Active Shape procedure introduced by Cootes and Taylor is presented. The new automated brain segmenta-tion and interpretation approach incorporates a priori knowledge about neuroanatomic structures and their speciic structural relationships to provide robust segmentation and labeling. The method was trained in 8 MR brain images and tested in 19 brain images by comparison t...

The generative surface reconstruction problem can be stated like this: Given a finite collection of 3D shapes, create a small set of functions that can be combined to generate the given shapes procedurally. We propose generative fact labeling (GFL) as an attempt to organize the iterative process of shape analysis and shape synthesis in a systematic way. We present our results for the reconstruc...

Medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .It is achievable by shape memory effect. For this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. Then shape memory effect was induced...
