Brain Morphometrics Using Geometry-Based Shape Transformations
نویسنده
چکیده
This paper presents a methodology for shape analysis of anatomical structures. A template shape is used as a unit, and a shape transformation mapping the template to a particular structure is used to quantify the shape of the structure with respect to the template. The geometric characteristics of the boundaries of the template and of an individual structure are used to deene corresponding regions between the template and the structure. These correspondences are then used to determine the shape transformation, which is based on an elastic adaptation of the template. Regional inter-subject and inter-population shape diierences are then identiied by comparing the corresponding shape transformations point-wise.

Statistical analysis of relative pose information of subcortical nuclei: Application on ADNI data
Many brain morphometry studies have been performed in order to characterize the brain atrophy pattern of Alzheimer's disease (AD). The earliest studies focused on the volume of particular brain structures, such as hippocampus and entorhinal cortex. Even though volumetry is a powerful, robust and intuitive technique that has yielded a wealth of findings, more complex shape descriptors have been ...
متن کاملCompensation of brain shift during surgery using non-rigid registration of MR and ultrasound images
Background: Surgery and accurate removal of the brain tumor in the operating room and after opening the scalp is one of the major challenges for neurosurgeons due to the removal of skull pressure and displacement and deformation of the brain tissue. This displacement of the brain changes the location of the tumor relative to the MR image taken preoperatively. Methods: This study, which is done...

The aim of this study was to determine the variations among cephalic plates of individuals in two populations of Clinopodes flavidus in Alborz Mountains, by means of landmark-based techniques of geometric morphometrics. Therefore, 17 landmarks and semi-landmarks on the coxosternite of poison claw and seven landmarks and semi-landmarks on the tarsangulum of poison claw were selected using TpsDig...

Morphometrics, a new branch of statistics, combines tools from geometry, computer graphics and biometrics in techniques for the multivariate analysis of biological shape variation. Although medical image analysts typically prefer to represent scenes by way of curving outlines or surfaces, the most recent developments in this associated statistical methodology have emphasized the domain of landm...
