Abstract: A multi-leaf collimator can comprise two banks of leaves facing each other across the radiation field, and an actuation member or actuation means configured to control the location of each leaf, for example, to control the degree to which each leaf is extended into the radiation field. The leaves of the multi-leaf collimator can comprise at least one radioluminescent marker that can emit illumination light, which can be used to accurately determine the position of the leaves.

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 method of controlling a radiotherapy device, a computer readable medium and a radiotherapy device are disclosed. The radiotherapy device includes a radiation source coupled to a rotation means. The method includes applying radiation to a subject using the radiation source and rotating the radiation source around the subject using the rotation means according to a first fixed rotation scheme. The method further includes, during execution of the first fixed rotation scheme, determining that the subject is in a suboptimal position, pausing application of the radiation by the radiation source and logging a first angle of rotation of the radiation source at which application of the radiation is paused.
