Abstract
The present invention provides a radiation detector which comprises a tube and detector elements distributed over the tube. Such an arrangement can be used to provide information on a radiation beam prior to interaction with a patient and after interaction with the patient. The detector is particularly compact and therefore suited to use with apparatus where space is restricted. By a particular arrangement of detectors and optical fibers, the detector can provide data at all angles of rotation.
