[Gate-users] pinhole collimator

[Gilberto Almeida]

Hello gate users,

I'm a newcomer with GATE, and my first big problem is how to parameterize a
pinhole collimator in SPECT Head... I've searched everywhere but haven't
found anything...

 I want to parametrize a pinhole with 0.1cm of height, 0.1cm of radius and
30 degrees of acceptance angle.

 I'm using version 3.1.2 of GATE.

 Thank you for your help
