Hi All

I have use the CudaFDKConeBeamReconstructionFilter  algorithm to
reconstruct a set of CBCT images,
1. )but I found that each slices contains blurry image area , because I was
using a flat panel detector   , so I tried to adjust the source offset ,
inofplaneangle and outofplaneangle , but the blurry image area  still at
there, could this be due to detector motion blur effect? Or is there a
suggested way to correct it?

2). From the reference http://www.openrtk.org/Doxygen/DocGeo3D.html I can
know that adjusting the source offset and inofplaneangle / outofplaneangle
can ensure that the detector remains parallel to the source, But how can I
make sure that the Z-axis of the ISO, the detector and the source are also
kept parallel at the same time, Can I achieve this by adjusting any
parameters or using any method?

The picture below is my result  for Question 1.

thanks for your reply,
