Abstract: A wireless signal transmitter is provided for a radiotherapy device, said radiotherapy device being configured to provide radiation to a subject via a source of radiation, and further being configured to output a non-continuous beam of radiation, wherein said non-continuous beam of radiation has a first, time-related property associated therewith. The wireless signal transmitter is configured to wirelessly transmit a signal comprising data regarding the first, time-related property that is associated with the non-continuous beam of radiation, to a wireless signal receiver.

Abstract: A radiotherapy apparatus is disclosed, with a linear accelerator for producing a beam of electrons, a target aligned with the electron beam, the target being capable of producing photons when electrons are incident thereon, and a material which is capable of producing neutrons when photons of sufficient energy are incident thereon. A neutron detector capable of providing a signal to a controller of the linear accelerator is provided, the controller being capable of varying the energy of the electrons of the electron beam.

Abstract: Systems and methods are disclosed for detecting Cherenkov radiation produced during radiotherapy. A radiotherapy system comprises a patient receiving space for receiving a patient, a therapeutic radiation source, and a light detector configured to detect Cherenkov radiation subsequent to the emission of therapeutic radiation. Optionally, the system may make use of a optically transmissive dielectric to produce Cherenkov radiation.

Abstract: Disclosed herein is a method for controlling a radiotherapy apparatus to perform quality assurance. The radiotherapy apparatus comprises a subject support surface, and a beam delivery device for delivering a planned radiation dose to a moving target region of a patient according to a plan, the plan comprising instructions for instructing the beam delivery device to adjust a positioning of a beam to compensate for motion of the target region. The method comprises receiving motion data, controlling movement of the subject support surface to simulate motion of the target region of the patient, based on the motion data, and controlling the beam delivery device to deliver radiation according to the plan while the subject support simulates motion of the target region.
