Hello RTK community,
I am afraid that my question might not be directly related to the
excellent implementation we are all using, but it might still be
interesting for some of you.
I have a stack of 1500 projections of size 2048*2048. I obviously can't
reconstruct the full resolution volume on my graphics card, as it is too
big. So my solution was to split the sinogram into N parts, for which
each reconstructed volume would fit in my GPU memory and then reassemble
them. I did a test with a 700*820*900 sinogram, that I cut in two parts
of 700*410(+a small overlap)*900.
While the reconstruction of the whole volume was acceptable, I got a
weird issue with the split ones: the one corresponding to the top of the
image is also ok, but the bottom one is very blurry. The three images
can be found at the following links:

I used the same calibration parameters for the three reconstruction. I
visually checked the split sinograms and they looked fine.
Any insight will be much appreciated !
Thanks in advance,
kindest regards,
Vincent
