Abstract: Disclosed herein is a method of positioning a patient for radio-therapy treatment using a radiotherapy device. The method comprises determining an identity of a treatment beam that is to be used to treat the patient, determining an offset between a reference location and an isocentre location for the identified treatment beam that is to be used to treat the patient, and changing a spatial relationship between the patient and at least a part of the radiotherapy device, according to the determined offset.
