Abstract
Disclosed herein is a computer-implemented method of determining a control scheme for operating a radiotherapy device for delivery of a radiation dose via a radiotherapy treatment beam to a target. The radiotherapy device comprises abeam generation apparatus that is configured to output radiation via a radiotherapy treatment beam, and wherein operation of the radiotherapy device can be described using at least one operational parameter. The method comprises determining the control scheme by identifying a first time (t) at which at least a first portion of the radiation dose is to be delivered at a first radiation delivery rate; and identifying a second time (t) for the radiotherapy device to undergo a cool-down period, wherein during the cool-down period the radiation delivery rate is less than the first radiation delivery rate; wherein the control scheme is determined such that at least one criterion associated with the at least one operational parameter is met.
