[Gate-users] SPECT zoom settings

[Miriam Dixon]

Hi Gate Users,

I am looking to simulate a physical SPECT system as closely as possible.
The process for the scan I am simulating is for the output to be a 64 x 64
pixel matrix, with pixel size of 6.59134 mm x 6.59134 mm, with a zoom of
1.4. In the GATE documentation, the only reference to zooming I can find is
in relation to the visualization, which isn't what I'm looking for.

The idea I have at the moment is to reduce the pixel size by a factor of
1.4, so a smaller area is imaged, then magnify the output by a factor of
1.4, to get the same overall effect. Does anyone have experience with this,
or with another way to achieve the 1.4 zoom?

Cheers,
Miriam
