[Gate-users] STIR-strange hot voxel in the center

Dear Gate Users,

I´m using STIR as reconstruction tool. In the reconstructed images there is
always a hot voxel right in the center of the FOV apparent, which does not
belong to the imaged phantom. This effect does not occur when using
iterative reconstruction methods instead of FBP. I´m not sure if this is a
problem arising from STIR or from the measured data it self.
Any ideas or suggestions would be appreciated.

Best regards,
