Detailed Description

The primary generator action class with particle gun.

The default kinematic is a 6 MeV gamma, randomly distribued in front of the phantom across 80% of the (X,Y) phantom size.

The primary generator action class with particle gum.

The default kinematic is a 6 MeV gamma, randomly distribued in front of the phantom across 80% of the (X,Y) phantom size.
