My code and data-set are attached in the previous discussion. Also parameters for generating geometry explained in the same thread. I am working without creating geometry.xml but creating geometry in the code itself.

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. Simon On 18/04/2016 08:50, AMJAD N wrote: Hi, The data set is reattached below,.

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 -------------- next part -------------- An HTML attachment was scrubbed...
