FlexiPlan - Path Planning for Deformable Robots in Complex Environments

[Russell Gayle et al.,Systems and Science, 2005]

Application: Liver Chemoembolization

A long thin catheter is navigated from the femoral to the hepatic arteries near a tumor in the liver for direct drug injection.

FFT Applications

[Thomas Jansen et al., VMV 2004]

Filtered Back-Projection

Create volume from projections

Blending of “FFT-filtered” projections

Visualization of intermediate results!

Faster by an order of magnitude!

4.5 min (CPU) vs. 24 sec (GPU)

Fourier Volume Rendering

Inverse Filtered Back-Projection

Slice in frequency = Projection

Needs high-quality interpolation

512³ rendered in >25 frames/sec

But needs slightly more space!

Glift : Generic, Efficient, Random-Access GPU Data Structures

[Aaron Lefohn et al.,

ACM TOG, 2006]

STL-like abstraction of data containers from algorithms for GPUs
