[Gate-users] Variance Reduction Technique on GATE v6...

Dear Gaters,

Long time no see~ :)


Anyway, in these days I am working on the VRT in GATE v6.

However, I just find two options in the official users guide,
Splitting and russian roulette.

]


In the mean time,

1) is there those two implemented VRTs on ROOT v6.0 p01?
I saw there is the other VTR on CT projector, which is not NM.

I saw Beenhouwer's paper which described two VRTs and enhanced about 5 times.
On the Staelens's paper, they are working on the forced detection.

I guess...Using filter could be an option to enhance the speed.
but it's not primary VRTs, right?


2) Is it working on the other process except Bremsstrahlung?

I just can see the code on Bremsstrahlung on users manual.

I'm working on it in these days,
but ROOT analysis is now working properly on our cluster.

so, just I like to make sure whether it's working on the other process or not.


Cordially yours,
MJ
