[Gate-users] Problems with GE Advance PET simulation

[Hyunkeong Lim]

Hi, GATE users.


I am simulating a GE Advance system in these days.

I referred to Dr. Schmidtlein`s paper in Memorial Sloan-Kettring Cancer
center (C. Ross Schmidtlein, Assen S. Kirov., et. al., "Validation of GATE
Monte Carlo simulation of the GE Advance/Discovery LS PET scanners",
Med.Phys 33(1), 198, 2006).

I made out a macro file with reference to GATE users guide.

However, I have a problem about random counts.

It is too many random counts compared with reference data.

I have doubts of digitizer module or data processing after simulation.

I tried to fine some solutions but I couldn`t find clearly solutions.

My macro file is attached for helping appreciation these problems.

Could you please command some advice for that simulation?



Thanks.

Hyunkeong.
