[Rtk-users] SPECT reconstruction issue

[Nathan Sinsoilliez]

Hello everyone,

I'm currently using rtk to reconstruct SPECT images using OSEM and I have
an issue after the reconstruction. The total count of the image is
completely changed (like 8E+6 in the projections VS 2E+4 when
reconstructed). Also most of the pixels now have decimal values.
Graphically everything seems to be alright though.

Do you have an idea about what could cause this problem ?

Best Regards
Sinsoilliez Nathan
