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 at increased distances where r 2 ΔΩ=ΔS >> so that the cone opening is greater than voxel cross section
