Figure 9
Illustration of the two-step interpolation scheme. First, a new grid is chosen for a given direction, k, and the partial absorption Au,v is calculated at every grid point using bi-linear interpolation and accumulated along k. In the second step, the partial absorbance seen by a given voxel, Bxy, is backinterpolated from the new grid by trilinear interpolation to a point one half-slice behind the voxel to avoid double counting the voxel of interest.
