about voxel size in the reconstruction image

[zjZhao714]

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.
