x-ray imaging using 3x4 projection matrices [message #49169]

Hello,
Can someone please help with this problem?
I have a set of 3x4 projection matrices describing an X-ray system in
which the detector plane remains fixed, and the X-ray source moves in a
limited arc around some object, taking projection images. Therefore,
the detector plane is *not* perpendicular to the central ray-line
(except for the middle, or "zero angle", projection). I have a unique
projection matrix for each angle.
I would like to simulate projecting x-rays through a my own virtual 3D
object to this 2D plane for any given projection angle using the 3x4
projection matrices that I have. Does anyone have some code for this,
or some advice as to how to proceed? My knowledge of using such
matrices is limited.
Regards,
Mark
