Key Investigators

  • Marine Clogenson, Charles Baur (EPFL: Swiss Federal Institute of Technology)

Project Description

Objective

  • The goal of the project is to generate a 3D model of the C2 cervical vertebra for surgery planning using an atlas-based segmentation technique.
  • A Statistical Shape Model of the C2 vertebra has been created from 91 CT scans using Statismo [1], a toolkit for building PCA shape models.

Approach, Plan

  • A first loadable module for displaying a statistical shape model (SSMDisplay), which allows visualizing the main variation of the shape, has been implemented. Some small bugs still have to be corrected.
  • A second loadable module for landmark constrained shape model fitting (LandmarkSegmentation) is in development to perform interactive segmentation of the vertebra.

Progress

  • Development of an Extension with the two loadable modules
  • Move to the new version of the Superbuild to integrate two external libraries: Statismo and Hdf5
  • Resolution of some bugs in the SSMDisplay module
