[Gate-users] mac-files

[Pietrzyk, Uwe]

Hi Pat,

please find attached hit collection of mac-files, which
I use for the generation of projections. Note, that this
example is of a similar configuration than the EduGATE-
example: Gamma_Camera, where we created a configuration
file to easily modify parameter.
Try to take a low activity, switch on the visualization and
watch the camera circulating around the source …

I checked your projection file and it doesn't look wrong,
but indeed, also not quite right. Did you acquire a full
circle?

Best wishes and kind regards

U. Pietrzyk
