BUFGIX: correct TOF kernel truncation (taking tof bin width into account) #70

Closed gschramm closed 5 months ago

gschramm commented 5 months ago

supposed to fix https://github.com/gschramm/parallelproj/issues/69

KrisThielemans commented 5 months ago

yes. this fixes all the problems I saw. backproj is now essentiallly the same as for the STIR ray-tracing matrix. forward projection is now also nice. This is for a disk with a smaller disk as insert.

Great. Should end up in a new release this weekend.

In this plot it seems that PP (blue) line is zero everywhere. Is that the case or a plotting artifact?

KrisThielemans commented 5 months ago

sorry, copied the wrong plot! In the actual one, you cannot see PP as it's "behind" RT
