1. A radiotherapy device comprising:
a source of therapeutic radiation; and
an imaging system, the imaging system comprising:
a source of imaging radiation; and
a detector;
wherein the imaging system is switchable between a first configuration and a second configuration, wherein, in the first configuration, the imaging system is configured to emit a beam of imaging radiation shaped for a first imaging modality toward the detector and, in the second configuration, the imaging system is configured to emit a beam of imaging radiation shaped for a second imaging modality toward the detector, wherein the detector has a shape formed by at least a first section and a second section, wherein the first section and the second section intersect with one another, wherein the first section is positioned for receiving the beam of imaging radiation for the first imaging modality, and wherein the second section is positioned for receiving the beam of imaging radiation for the second imaging modality, and wherein the detector comprises:
an array of tileable photodetectors each configured to provide a signal indicative of an intensity of imaging radiation incident thereon.
