about voxel size in the reconstruction image

Open zjZhao714 opened this issue 1 year ago • 2 comments

Dear villekf,

I'm sorry to trouble you so many times. I want to know how to modify or decision the voxel size in the reconstructed image? And I also want to know why the list-mode reconstructed image arise too much noise and artifacts?(The example in Inveon_PET_main_listmode_example.m, and I don't modify anything.)

Best wishes.

Not sure if this is applicable anymore, but the FOV size and the number of voxels in the image decide the voxel size. For example if FOV size in the x-direction is 100 cm and you have 200 pixels in the x-direction, the voxel size is 0.5 cm.

As for the list-mode example, which of the two reconstructions are you referring to? Neither of them have been optimized in any way so the quality is also not optimal. I can't test them at the moment, but I'll try to check them out in the future.

Thank you very much, and now I know how to do it.
