[Gate-users] Need your help on CT simulation about how to get the hits happened in phantom

[bearboysj at sina.cn]

Dear gate users，
I am using vgate（gate-v7.2）on CT simulation, and I am new. I used the benchmarkCT.mac in this vgate, the mac files are in corresponding directory  : /home/gate/Progs/Gate/gate_v7.2/examples/example_CT/classic.
I want to use a sensitive detector on the phantom , so I added some lines at the end of  the file ofphantom.mac as below:
/gate/waterCylinder/attachPhantomSD
/gate/aluminiumBall/attachPhantomSD
/gate/PVCBall/attachPhantomSD
/gate/glassBall/attachPhantomSD/gate/spineBoneBall/attachPhantomSD
and I set setRootHitFlag in output.mac as below:/gate/output/root/setRootHitFlag 1
but from the hits recorded in the benmarkCT.root, the Z of all hits are as below:obviously, the Z of hits are in the range of [150mm, 151mm], that is in the silicon detector. Then my question is how I can record the hits happened in the phantom?
I need your help. It is very kind of you to show me the right way to do this.
Sincerely Xiong Shou-Jian
