[Gate-users] voxelized phantom setup

[Naser Darwish]

Dear gaters,

I am having trouble setting running the XCAT with GATE. I am able to
generate the act.bin and atn.bin for the phantom and for the source. I then
add them up. Some things I am not sure still is how to specify the source
with to a contrast ratio of 8 to 1 and how to specify activity (e.g.
15mCi/70kg).

I use medcon for converting the binary files to uint16 using the following
command:   medcon -f act.bin -c intf -i
This generates a m000-act_1.h33 and and m000-act_1.h33.
For GATE, I specify the attenuation range as below and the activity range
following. I know the activity is wrong but I am just trying to see if I can
get GATE to do the simulation without errors and I will correct the activity
when I know how to specify it. Now I get an error also listed below. I
appreciate your help greatly!

If I use the example in GATE for voxelized source with the brain_phantom,
the simulation runs with no errors

Best regards,
Naser
