Anisotropic Diffusion for Direct Haptic Volume Rendering in Lumbar Puncture Simulation
The segmentation of patient data often is mandatory for surgical simulations to enable realistic visual and haptic rendering. The necessary preparation time lies in the range from several hours to days. Here we augment a direct haptic volume rendering approach for lumbar punctures by edge-preserving smoothing preprocessing. Evaluation is carried out on user defined paths. Compared to our reference system force output can be improved over non-preprocessed image data.
