Dear Amjad,<br>
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?<br>
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.<span><font color="#888888"><br>

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