Exercise9 - CBCT [VRT]

Now create a simulation from scratch: the goal is to simulate the acquisition of a x-ray cone-beam radiography. Create a world containing a patient ct image and a detector located about 50 cm away from the patient. Add a photon source emitting gamma of 60 keV energy, with a 8x8mm square and a divergent beam, pointing to the patient and the detector. Record the photon fluence on the detector by using a FluenceActor (photon counting). The goal is to produce two radiographies of the patient, at 0 and 90 degree.
