[Gate-users] Spect pin hole collimator

[Débora Salvado]

Hi Mauro,

Have you checked the SPECT example in the examples folder of GATE?
A parallel-hole collimator is defined there. The idea is that you have a
mother volume made of lead or any other suitable material and then add
small air holes to construct the collimator.

My suggestion for a pinhole collimator is that you use two air "trap"
volumes inside a "box" of lead. The pinhole aperture defined by the size of
the "trap" volumes.

Good luck with your work,
Regards,
Débora

Dear all
My name is Mauro and I have been working on gate since two weeks so far.
gate is not very easy for me and I need to construct a pinhole collimator
geometry, but I can't understand how to write the volume about the pinhole.
Can anyone help me or give any general suggestion to me.
Thank You very much
Kind Regards
Mauro
