Fast volumetric deformation on general purpose hardware
Christof Rezk-Salama,Michael Scheuering,Grzegorz Soza,G. Greiner +3 more
- 01 Aug 2001
TL;DR: A novel approach is presented, which adaptively subdivides the volume into piecewise linear patches and an appropriate mathematical model based on tri-linear interpolation and its approximations is proposed, which demonstrates the significant performance benefit and allow for time-critical applications, such as computer assisted surgery.
Hybrid Visualization for White Matter Tracts using Triangle Strips and Point Sprites
TL;DR: The presented approach is faster than existing techniques of similar visualization quality and at the same time allows for real-time rendering of dense bundles encompassing a high number of fibers, which is of high importance for diagnosis and surgical planning.

TL;DR: In this article, the authors present an intraoperative augmented reality system (IARS) that directly projects preoperatively planned information and structures extracted from CT data, onto the real laparoscopic video images.

Enhanced 3D-Visualization of Intracranial Aneurysms Involving the Skull Base
F. Vega Higuera,N. Sauber,Bernd Tomandl,Christopher Nimsky,G. Greiner,Peter Hastreiter +5 more
- 15 Nov 2003
TL;DR: 3D-visualization of intracranial aneurysms making use of transfer functions based on measured values and gradient magnitudes extracted from the CTA data is introduced and a tool for the creation of 2D transfer functions in the clinical environment is presented.
Automatic adjustment of bidimensional transfer functions for direct volume visualization of intracranial aneurysms
Fernando Vega Higuera,N. Sauber,Bernd Tomandl,Christopher Nimsky,G. Greiner,Peter Hastreiter +5 more
- 05 May 2004
TL;DR: This work introduced the use of bidimensional TFs based on measured intensities and gradient magnitudes for the visualization of aneurysms involving the skull base through a registration of respective 2D histograms, making it possible to successfully use bid dimensional TFs without technical insight and training.
