Virtual surgery Position: Supervisor Funding: / Duration: 2000-2003

Project description

In this ongoing project, we investigate techniques which are necessary to generate, model and deform 3D data for applications related to virtual surgery:

• Generation of photorealistic 3D surface data
  • Stereo photogrametry
  

• Generation of slices of body sections from generic slices and a 3D surface model
  • Generic slice contour deformations according to sliced 3D surface models
  • Generic slice deformations according to somatotypes (Endormorphy and Mesomorphy) of individuals
  

• Generation of 3D volumetric meshes of body organs and structures from slices of body sections
  • Marching cube algorithm
  
  • Mesh decimation
  

• Real-time deformation of 3D models
  • 3D interface
  • Spring-mass system
  • Collision algorithm
  

• Soft tissue deformation from 3D surface data
  • Generation of 3D volumetric meshes of soft tissues from 3D surface data (generated from 3D scanners)
  • Implementation of a finite element model (FEM) for soft tissue deformation
