Dear Zahid,
We do not need the projections file, at least not for a first stage of
error tracking. We only need the header.
Try the following command line:
rtkprojections -p . -r yourProjectionsFileName -o proj.mhd
It should write a "proj.mhd" and a "proj.raw". The "proj.mhd" file is
what we need, and it is a very light text file. The "proj.raw" contains
the pixel values, but at the moment we do not need them. We will create
our own proj.raw file, filled with zeros, which should be enough to
track down the error you encounter.
Looking forward to receiving your file,
Cyril

Dear Sir,
The single raw file of the projections is 1.4 GB and we are not
able to send this big file to you. Can you please suggest other alternatives
for this?
Or can you provide us the PC configuration to solve the issue?
Let me know if any other clarification is required.
Thanks & Regards
Zahid Hasan Ansari

Hello Zahid,
We will need the header of your projections file, too (It is best if you
have all your projections as a single .mhd and a single .raw file, so it
should be 3-D image, and you send only the .mhd file).
Regards,
Cyril

Dear Cyril Mory,
I have only used RTK version 1.3.0. but in the error
message it is showing RTK version 1.2.0.
Please find the attachment of the geometry file of our
projections.
Thanks & Regards

Dear Zahid,
Without some more information, it's unlikely that we find the source of
the problem. Here are a few things you can do to help us (and therefore
yourself):
- try version 1.3.0 of RTK: there have been considerable changes in the
Cuda forward and back projection filters since v1.2.0, so your problem
might disappear just by upgrading to the new version
- create a small example that reproduces your problem. You can, for
example, simulate a geometry, simulate projections of a shepp logan
phantom, and reconstruct from these projections (take a look at
http://wiki.openrtk.org/index.php/RTK/Scripts/FDK if you need an
example). And send us the script
- OR send us your geometry file and the header of your projections file
(no need to send the projection data itself, we'll create a zero-filled
stack of projections), and the command line that crashes
Best regards,
Cyril

Dear Zahid,
There is no screenshot so I'm guessing that the problem is a CUDA
memory
error. If you use the command line tool rtkfdk, you should first make
sure
that you use the --lowmem option to stream the projection images. If
it
is
no sufficient, you can split your volume using the --divisions. The
corresponding C++ code can be found in rtkfdk.cxx.
Is Panacea Medical using RTK? We are happy to advertise the use of
RTK
on
our case studies webpage
