Statistical shape analysis of anatomical structures
… a computational framework for image-based statistical analysis of anatomical shape in different populations. Applications of such analysis include understanding developmental and anatomical aspects of disorders when comparing patients vs. normal controls, studying morphological changes …

Statistical Shape Analysis for the Human Back
… Procrustes and Euclidean distance matrix analysis (EDMA) have been investigated for analysing the three-dimensional shape and form of the human back. Procrustes analysis is used to distinguish deformed backs from normal backs. EDMA is used to locate the changes occurring on the back …

A statistical shape analysis of the neurocranium and long bones
… often fail to sufficiently capture the "true" shape of features, thus also failing to identify potentially important feature characteristics. The development of geometric morphometrics has allowed more comprehensive and accurate three-dimensional data capture which maintains the geometric …

Statistical shape analysis of neuroanatomical structures based on spherical wavelet transformation
… in vivo. Previous work in studying the shape variations of brain structures has provided additional localized information compared with traditional volume-based study. However, challenges remain in finding an accurate shape presentation and conducting shape analysis with sound …

Protection of Rear Seat Occupants Using Finite Element Analysis
… outlines the investigation of spleen and kidney shapes through statistical shape analysis. This type of analysis allows more customizable human body models which could better capture the injury probability to these organs for a wider range of the population. Finally, subject-specific models of …

Probabilistic Analysis of the Material and Shape Properties for Human Liver
… of this study was to quantify the variations in shape and material properties of the human liver. Statistical shape analysis was applied to analyze the geometrical variation using a surface set of 15 adult human livers recorded in an occupant posture. Principal component analysis was then …

Shape curve analysis using curvature
Statistical shape analysis is a field for which there is growing demand. One of the major drivers for this growth is the number of practical applications which can use statistical shape analysis to provide useful insight. An example of one of these practical applications is investigating and …

Late Complications in the Descending Aorta Following Valve-Sparing Root Replacement (VSRR) in Marfan Syndrome (MFS) Patients: A Computational Analysis
… fluid dynamics (CFD) simulations alongside statistical shape modeling (SSM) to investigate the relationships between aortic geometry, hemodynamic indices, and post-surgical dissection risk. We retrospectively analyze CT imaging of a cohort of MFS patients who underwent root surgery, divided …

Longitudinal analysis of three-dimensional facial shape data
Shape data encompass all the information that is left to describe a shape following removal of location, rotation and scale effects. Much work has been done in the analysis of two-dimensional shapes depicted by anatomical landmarks placed at points of importance. Less has been carried out in the …
