[Gate-users] How to use XCAT-attenuation information in Gate

[Wei Deng]

Hello, gaters. There is a question when I am studying the voxelized
phantom. It read 'AttenuationRange.dat' to form the attenuation map in
VoxelizedPhantom.mac in the examplePET. However the last column of
'AttenuationRange.dat' is not discripted as 'attenuation coefficient' but
'Tansparency'. Who can tell me the relationship between 'attenuation
coefficient' and 'Tansparency'? Should I replace the 'Tansparency' with my
'attenuation coefficient' when forming the attenuation map?
My phantom was created by XCAT. Is there any documentation (or are there
examples) for integrating XCAT-phantom
attenuation data into a gate simulation?

thank you so much for your attention.
Best regards,

Wei
