[Gate-users] How to obtain scattering signals?

[Janus]

Dear gate users,

Please can any expert tell me how to obtain SPR of one CT scanner projection? Also I want to output tree images, one scattering image, one primary image and the other resultant image (obviously the current CTScanner output this image). 

At present I have obtained ROOT file in the detector, but I do not know:
1) should I extract scattering photons and primary photons from hits or events?
2) how should I differenciate compton/primary photon from the phantom but not in the detector?   

Any comments or suggestions would be greatly appreciated. 

Regards,



Janus
