1. I need to be efficient
Can the CC method be both efficient
AND accurate…?
The less scerma varies the more I
can reduce the number of
directions
(increase of efficiency)
without a considerable loss of
accuracy
The approximation by CC that scerma is
transported linearly will only break
down (ray artefacts) at increased
distances where r

ΔΩ=ΔS >>
Discretization artefacts decrease for:
•
coarse voxel resolution
(voxel cross section ~ ΔS)
•
Rapidly decreasing kernels
