Dear Amjad,
I had a quick look at your dataset. For sure, it's a geometry problem.
Do you have any information regarding the geometry? How did you obtain
sdd / sid?
Currently, I can see that you have set the projections and the volume
origin to 0,0,0 which is not correct, you probably want to center them
for a first test. If you want to center them, the formula to compute the
origin is -0.5*spacing*(size-1) for each corrdinate.

Hi
I am new to RTK. and I have been looking into it for the past two
weeks..I
think its an amazing tool..
My problem is:
I have a set of 50 raw CT scan projections of an industrial fin as
shown
(fin.jpg)
I am reading it using ImageSeriesReader with RawimageIO and been have
trying to reconstruct it using FDKConeBeamReconstructionFilter.
Its been
almost a week that I am trying this,but
I could not reconstruct it correctly
I tried varying my geometry, origin, spacing etc ..but still no hope
Can u please look into my program(finRecon.txt) and the current
output I am
getting is output_fin.mha , which is incorrect and suggest some help
The link to my dataset:
http://expirebox.com/download/b523394ea63c635d10171a69e687993b.html
raw image dimensions : 1032 *1012
raw image 16 bit
current spacing: 0.05 0.05 0.05
origin: 0 0 0
step angle 7.2 degrees
Thanks in advance,
AMJAD
