Dear castor-users,
I’m trying to reconstruct GATE simulations of an octagonal small-animal scanner used for testing. The reconstruction is performed with the incremental Siddon projector in histogram mode, using an image-space psf. I attach an image to show you the artefacts that are produced.
Could they be related to the absence of the normalization correction?
I have simulated with GATE a hollow cylinder to use for normalization, but I can’t understand how to provide the correction to the software.
Thank you
Alessandro
