[Rtk-users] DRR image generation from 3D CT

[Simon Rit]

Hi,
Look at the doc on the geometry file
<http://www.openrtk.org/Doxygen/DocGeo3D.html> and rtksimulatedgeometry
<https://github.com/SimonRit/RTK/tree/master/applications/rtksimulatedgeometry>
for creating one file. AddProjection
<http://www.openrtk.org/Doxygen/classrtk_1_1ThreeDCircularProjectionGeometry.html#a39d6a67147cac1f2b5d75f5958a48f9a>
takes several parameters. Given your scheme, it should look like
AddProjection(1000, 1536, angle, +/-190 etc)
It looks like an Elekta geometry given the distances, check the example here
<http://wiki.openrtk.org/index.php/RTK/Examples/ElektaReconstruction> if
you can get access to the database.
