[Rtk-users] Half beam CT

[Vincent Libertiaux]

Hello RTK gurus,

I have a question about half beam CT.  I performed a simulated CT with a 
detector displaced by half of its width and everything went smoothly.  I 
got a nice reconstruction.
I then ran the same simulation but moved the object rather than the 
detector this time (for practical reason, it is more likely to happen in 
our real xray shots). In the rtk geometry, I imposed proj_iso_x and 
source_x to be the same value, thus modelling a displacement of the object.

Unfortunately, I get a ITK ERROR: Cannot account for detector 
displacement larger than 50% of panel size.

The detector displacement is the same in both cases, so I can only 
assumes the problem comes from shifting both the source and the detector ?

Did I do something wrong ?

Thank you in advance for any help !

Best regards,

Vincent
