[Rtk-users] Simple FDK reconstruction using SimpleRTK does not work

[mathis.hoffmann at fau.de]

Hello,

we currently try to set up a simple FDK reconstruction pipeline using 
SimpleRTK for research purposes. We have projections from a simulated 
Forbild phantom and the corresponding projection matrices. We can 
reconstruct the same data trouble-free using our internal tools. 
However, we fail to do so using SimpleRTK. We provide the data including 
a minimal example that demonstrates the problem here: 
https://www.dropbox.com/sh/8fqhyvcnzb5u8zd/AAAYLQ50_3GIoTSMli5nmtYca?dl=0

Could someone please have a look on the problem? We have tried for a 
long time now. The relevant geometry parameters (which are also set in 
the script) are:
Detector offset in u/v direction: 255.5/255.5
Pixel sizes u/v: 0.8/0.8
Size of projections: 512x512
Size of volume: 512x512x512
Voxel sizes x/y/z: 0.5/0.5/0.5
Midpoint of volume: 0/0/0

Thank you in advance for any help!
