摘要： A method monitors radiation incidence onto an object being prepared for and/or undergoing radiation delivery. The monitoring method includes: emitting a light field onto a surface of an object being prepared for and/or undergoing radiation delivery, the light field at least substantially corresponding to radiation incidence of the radiation delivery; monitoring the light field being reflected from the surface of the object; and processing the monitored light field to determine the radiation incidence of the radiation delivery relative to the object at least partially based on the monitored light field.

摘要： A patient monitoring system for monitoring a patient undergoing radiotherapy comprising a projector operable to project a pattern of light onto a patient undergoing radiation treatment, a patient restraint operable to restrain the patient relative to a treatment apparatus, an image detector operable to obtain images of the patient, and a model generation module operable to process images of the patient obtained by the image detector to generate a model of the surface of a portion of the patient, wherein at least a portion of the patient restraint is colored and the model generation module is inhibited from generating a model of the colored portion of the patient restraint.

摘要： A method of identifying portions of a model of a surface of a patient which can be used to identify to position of a patient is provided. A pre-existing model of the surface of a patient is utilised to generate simulated images of the projection of patterns of light onto the surface of the patient. The simulated images are then processed to generate a further model of the surface. Any differences between the model generated by processing the simulated images and the original model surface identifies portions of the surface which cannot be reliably modelled and hence portions of a surface which should not be used to monitor the positioning of a patient. The invention has particular application for identifying the reliability and accuracy of generated models of the surface of a patient used for monitoring and positioning a patient undergoing radiotherapy.

摘要： Some embodiments are directed to a monitoring system for monitoring the positioning of a patient relative to a treatment apparatus operable to deliver radiation along a radiation path. A model generation module is arranged to generate a model of a surface of a patient being monitored. A comparison module determines a transformation required to match the generated model to the stored model target surface. An offset determination module then utilizes the transformation and data indicative of a current position of a treatment apparatus to determine an offset value indicative of the offset of the surface of a patient relative to an axis corresponding to a determined current radiation path for radiation generated by the treatment apparatus applied to a patient. If the offset value exceeds a threshold, a warning may be generated or treatment may be halted.
