[Gate-users] Multi-step rotations

[Ben McDonald]

Hi Gaters,

I'm interested in tilting pinholes toward a common volume in a 
multi-pinhole aperture. To do this in GATE, I'm appropriately 
translating and rotating two back-to-back cones to form one pinhole.
I'm running into problems when I try to perform multiple rotations, 
first say around the y-axis to get the first cone oriented in the 
collimator plate, and second around the z axis to tilt the cone towards 
the FOV. Only the last rotation actually occurs, starting from the 
initial configuration of the volume.

This same issue has been raised before 
(http://lists.healthgrid.org/archives/gate-users/2006-December/001613.html), 
but I could not find any responses.

Any ideas?

Thanks,

Ben McDonald
