Illustrative Rendering of Dense Line Data
We present a technique for the illustrative rendering of 3D line data at interactive frame rates. We create depth-dependent halos around lines to emphasize tight line bundles while less structured lines are de-emphasized. Moreover, the depth-dependent halos combined with depth cueing via line width attenuation increase depth perception, extending techniques from sparse line rendering to the ill...
متن کاملMethods to Improve Fiber Reconstruction at DTI-Based Tractography in the Area of Brain Tumor: Case Illustration and Literature Review
Background and Aim: DTI-based tractography could help us to visualize the spatial relation of fiber tracts to brain lesions. Several factors may interfere with the procedure of diffusion-based tractography, especially in brain tumors. The aim of the current study is to discuss several solutions to improve the procedure of fiber reconstruction adjacent or inside brain lesions. Illustrative cases...
متن کاملAnalyzing and Reducing DTI Tracking Uncertainty by Combining Deterministic and Stochastic Approaches
Diffusion Tensor Imaging (DTI) in combination with fiber tracking algorithms enables visualization and characterization of white matter structures in the brain. However, the low spatial resolution associated with the inherently low signal-to-noise ratio of DTI has raised concerns regarding the reliability of the obtained fiber bundles. Therefore, recent advancements in fiber tracking algorithms...
متن کاملPreservation of the optic radiations based on comparative analysis of diffusion tensor imaging tractography and anatomical dissection
BACKGROUND Visualization of the precise course of the visual pathways is relevant to prevent damage that may inflict visual field deficits during neurosurgical resections. In particular the optic radiations (OR) are susceptible to such damage during neurosurgery. Cortical pathways can be mapped in vivo, by using Diffusion Tensor Imaging (DTI). Visualization of these pathways would be potentiall...
متن کاملThe Benefits and implementations of Diffusion tensor imaging and Neural Fiber Tractography in Brain Surgery
Background and Aim: The methods for detecting brain activation with fMRI, MRI provides a way to measure the anatomical connections which enable lightning-fast communication among neurons that specialize in different kinds of brain functions. Diffusion tensor imaging is able to measure the direction of bundles of the axonal fibers which are all aligned. Besides mapping white matter fiber tracts,...
