[Gate-users] Phantom Placement Translation

[Xinjie Cao]

Dear all,

I am trying to shift a voxelized body phantom along the y-axis with 90
degrees rotation angle along the z-axis. Although the phantom was shifted
to the right position with the right angle, there was always an original
phantom left at the center of the FOV, as you could see in the
following image:

The top one marked by the red circle is the phantom after the right shift
and the bottom is the original phantom at the center of FOV.

The visualization and the phantom parts of the macro are as follow:
==========================================================

*/vis/viewer/set/viewpointThetaPhi   0 0/vis/viewer/zoom

Does anyone have some idea why there is a phantom left at the center? Any
answer will be highly appreciated! Thanks!

Best,
Xinjie
