Generation of Surface Models from Segmented, Medical Image Data


Surface models from medical image data typically suffer from artifacts such as staircases and terraces. Our goal is the (automated) generation of accurate and high quality surface models for surgical applications as well as simulations. The resulting surface models are evaluated regarding accuracy, smoothness, triangle quality (skewness), mesh resolution and homogeneity. The mesh generation process is focuses on image data preprocessing as well as postprocessing of the surface meshes (smoothing, remeshing, decimation).

Video 1
Sample video of realtime mesh smoothing with mouse movements mapped onto smoothing parameters.
Video 2
Sample video of realtime mesh smoothing. Quality measures, such as local errors, volume preservation, and curvature are computed in realtime.
Video 3
Sample video of realtime mesh smoothing. Parameter suggestions may be generated for patient-specific data based on only one parameter - the target smoothness.
