UNC SPHARM-PDM Tutorial

ShapeAnalysisModule

Overview

Shape analysis has become of increasing interest to the medical community due to its potential to precisely locate morphological changes between healthy and pathological structures. SPHARM-PDM is a tool that computes point-based models using a parametric boundary description for the computing of Shape analysis. The point-based models computed with the SPHARM-PDM tool can be used in combination with the also UNC designed statistical tool shapeAnalysisMANCOVA to perform quantitative morphological assessment of structural changes at specific locations.

• Step by step analysis: With the ShapeAnalysisModule tutorial,you will learn how to load input volumes, run the module to generate triangulated surfaces with inherent correspondences and visualize them thanks to an intuitive quality control. Indeed,compared with previous versions, the ParticleModule is now part of ShapeAnaysisModule.
• Step by step analysis: With the ShapeAnalysisMANCOVA_Wizard tutorial, you will learn how to use this graphic interface to load meshes, run a group test in order to get statistical result, displayed through MRML scene.
