Abstract

A radiotherapeutic apparatus employs a collimator (52) set below a radiation source (50) and is adapted to move along an arc (54) substantially centered on the radiation source (50). As it sweeps the arc, the collimator (52) is adjusted so as to define the appropriate shape of radiation beam. A continuous sweep over the patient avoids edge artefacts and localized accumulation of leakage.
