| * | Fix scaling for fan/strip projector | Willem Jan Palenstijn | 2019-03-29 | 1 | -1/+26 |
| | | | | | | | | | | | | | The strip model for a fan beam geometry wasn't taking pixel magnification into account. Among other things, this resulted in diagonals through rectangles being weighted the same as hor/ver lines. This commit fixes this by scaling each pixel contribution by its magnification on the detector. This is only an approximation (since the magnification isn't constant inside the pixel), but since pixels are usually small, the error is also small. Unfortunately, computing this scaling factor is relatively expensive because it introduces a square root in the inner loop. | ||||
