[Gate-users] Using GATE to generate realistic PET images from XCAT phantom models

[Park MinJae]

Dear Andinet,

Take a look at "examples/example_PHANTOM_SOURCE/Voxelized_Phantom_Source"
in Gate source directory.

One more, in fact this is the best, GATE User's guide is pretty good.
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6:Voxelized_Source_and_Phantom

Hope you get the answer from there.

ps. It's amazing that kitware needs to PET images. :)
Are you gonna develop some image processing for PET in ITK?

Cordially yours,
MJ
