Hi,
FYI, I have opened the images. As far as I can guess from the sequence, the
circular trajectory of the source is very small wrt to the object size. I don't
know what I would do from such a trajectory. I would start by checking the

Hi,
I see one drawing only, not two. And the object does not seem to be

I hope this makes clear what trajectory i'm dealing with. Thank you.

Dear Robert,
Your description of the trajectory is very obscure to me. Maybe you have
a very unusual X-ray system. Could you make the following points clear :
- what is a PCB ?
- what is fixed/moving in your system (we need this information for the
object, the source and the detector), and w
Hello rtk users,
I have question to the RTK FDK Filter. As far as I understand from to the
fourier slice theorem the object to be reconstructed needs a circular
trajectory and needs to rotate its own centre.
Please have a look at the attached sketch. With this planar trajectory
