[Gate-users] Compton and the Rayleigh interactions within the phantom

[Auranuch Lorsakul]

Hi everyone,

I am simulating a CT scanner (32*0.6 x 672*1.4 mm) with a water phantom (33 cm diameter). I want to see the Compton and Rayleigh scattering within the phantom. So far I attached "PhantomSD" to the phantom and I could see small Compton scattering and none of Rayleigh scattering. I used the original physics.mac from the example CT folder. 

I could see a great amount of the Compton scattering on crystals (no Rayleigh occurred), which I expect to see in the phantom as well.

Could anyone suggest how to set those scattering on? 

Thanks,
Ney
