[Gate-users] translation of voxelizedphantom as a block?

[Howard]

Dear Gate Users,

I am trying to utilize the voxelized phantom as a beam block for X-ray.
First of all, I am not sure if this is feasible. If it is, then I'd like to
move the block to along the x-axis by, say, 30cm. I used the brain_phantom
as the voxelizedphantom. However, I found that the phantom was still at the
isocenter while the block had a displacement, as shown in the figure (
https://ibb.co/9HpXPCQ). For your reference, I am also attaching the macro
below.

Any suggestions would be appreciated!

Howard
