[Gate-users] how to add voxel source transformation matrix (if needed)

[David Sarrut]

Hello Alex & Seb,

sure it is possible ! You can "attach" the source to a volume and rotate
the volume, the source will rotate as well.

/gate/source/mysource/*attachTo* phantom

It is up to you to translate the source according to the coordinate system
of the "phantom" volume (by default, it is centered).

HTH,
David
