The in-air output ratio (Sc) for photon beams from linear accelerators describes the change of in-air output as a function of the collimator settings. The physical origin of the Sc is mainly due to the change in scattered radiation that can reach the

Head scatter factors for high energy photon beams from linear accelerators can be modeled using a two-source model consisting of focal and extrafocal radiation. The focal radiation can be approximated as a point source, and the distribution of the ex

An independent primary dose counter or totalizer has been developed for our linear accelerator. This counter is reset independently of the control console and thus will totalize the number of monitor units (MUs) delivered to the patient. This is espe
