Direct Haptic Volume Rendering in Lumbar Puncture Simulation

2012
The preparation phase for surgical simulations often comprises the segmentation of patient data, which is needed for realistic visual and haptic rendering. Expert segmentation of 3D patient data sets can last from several hours to days. In this paper we introduce a direct haptic volume rendering approach for lumbar punctures. Preparation time spent for

Strategies for direct volume rendering of diffusion tensor fields

IEEE Transactions on Visualization and Computer Graphics, 2000
Diffusion-weighted magnetic resonance imaging is a relatively new modality capable of elucidating the fibrous structure of certain types of tissue, such as the white matter within the brain. One tool for interpreting this data is volume rendering because it permits the visualization of three dimensional structure without a prior segmentation process ...

Occlusion-resolving direct volume rendering

2014
Direct volume rendering (DVR) is a powerful visualization technique which allows users to effectively explore and study volumetric datasets. Different transparency settings can be flexibly assigned to different structures such that some valuable information can be revealed in direct volume rendered images (DVRIs).

Direct volume rendering apparatus

The invention relates to a direct volume rendering apparatus for volume rendering a three-dimensional image data set. For each primary ray 10 of a plurality of primary rays, which traverse through the three-dimensional image data set and meet a respective pixel of a two-dimensional image in a two-dimensional image plane on which the three-dimensional ...
