RAPT
Monte Carlo Stereotactic Radiosurgery Simulation Software
Gamma Knife® Radiosurgery is a non-invasive medical procedure that uses beams of ionising photons from 201 60Co sources to treat intra-cranial lesions (Elekta/Leksell Gamma Knife). The Gamma Knife® unit comes with a treatment planning system - GammaPlan® - that uses an approximate description of the photon interactions within the head of the patient to calculate the energy dose deposited by these photons in the region of the tumour.
