Probabilistic model

Query

[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.

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!
