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
2
ΔΩ=ΔS >>
How increased …?
It depends on how rapidly the kernel
d
ith di t
ecreases w s ance.
Rapidly decreasing kernels are
more forgiving.
