[gate-users] gamma camera : pinhole modelisation (attachment : gamma camera macro)

I try to modelize a gamma camera with a pinhole
collimator (one hole and a cone with an insert at its
extremity used as a zoom).
When I do the simulation to study the sensibility of
my model, with a part of the insert on the cone of the
pinhole, my simulation gives bad results whereas when
i've done the simulation with the insert just near the
cone of pinhole, my results are good but reality is
not really modelised.
Someone know why?

Please help me.

Best Regards,

Faculty of medecine
