Dear developers,
For DRR image calculation i use a ThreeDCircularProjectionGeometry class
with AddProjection method. The default rotation direction is around
Y-axis in LPS coordinates (Z-axis in RAS coordinates in 3D Slicer) as i
understand from the documentation. Should i calculate rotation matrix
manually (using gantry, in-plane, out of plane angles) and then use
AddRotationMatrix method to simulate movement of gantry angle around the
Y-axis in RAS coordinates (and couch angle rotation around Z-axis in RAS
coordinates)? Are there any other options to setup a required axis of
rotation of the gantry?
Best regards,
Mikhail
