[Gate-users] interfile positioning

[kathy at physics.usyd.edu.au]

Hello all,

just a quick question re the positioning of the interfile input (for a
voxelized phantom). I know that the source must be translated by the
negative of half its dim's in the x/y/z directions. For the z direction,
will the resulting translation be equal to (negative):


0.5*(number of slices)*(slice thickness (pixels))*(scaling factor
(mm/pixel))

????

Thanks in advance for any help,

Kathy
