Hi,
I am trying to generate sinogram from scanned images of multi-pinhole SPECT system. After filtering I am trying to reconstruct object volumetrically and not slice by slice. Can anyone reply? or suggest any publications regarding this topic?
regards,
manu
Based on my experience with a multi pinhole SPECT, there is no conventional sinogram space as there is in a conventional SPECT.
In the multi pinhole SPECT that I used to work, there was 3 detector heads and the projections from each head was used for image reconstruction. Something similar to stiching method. However, these projections were called AKA sinogram.
Maryam Shirmohammad Thank you very much for your reply. I will go through your publications. may be these publications can help to solve my problem.
Thanks Again !

Of course you can produce "sinogram" data by using the same reordering process as used in ordinary SPECT. You only have to be aware that the meaning is different. In addition you have to take care if you are using multiplexing multi-pinhole collimation or not, if you want to interpret those "sinograms" correctly. If it comes to filtering, you must be aware of the fact that in multi-pinhole projections the information is much more complex encoded in a projection pixel compared to ordinary SPECT.
