Detailed Description

Test program to check consistency between projectors and LOR->detectors functions.

Tests detector points and LOR functions by checking intersections of LORs

Warning

Preliminary. Needs spanned but unmashed template projection data.

When trying different scanners/dimensions/voxels, run only in debug mode to catch asserts.

for some voxels, the round-trip in bin coordinates does not work (it ends up in the wrong plane). This is because the current axial-coordinate handling in this test is unsafe.

Todo

test stir::ProjDataInfo::get_LOR and stir::ProjDataInfo::get_bin

use stir::RunTests
