Abstract: 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.

Abstract: A radiation dosage monitoring system comprising a 3D camera operable to obtain images of a patient undergoing radiation treatment, the 3D camera being operable to detect Cherenkov radiation and any subsequent secondary and scattered radiation originating due the initial Cherenkov radiation emitted from a surface of the patient when the patient is irradiated by a radiation beam; and a processing module operable to process the images obtained by the 3D camera utilizing data indicative of chromophores present in a patient's skin to apply a correction factor to such images to account for absorption of Cherenkov radiation by chromophores in the skin when utilizing the images to generate a representation of radiation applied to the surface of the patient.

Abstract: Some embodiments are directed to a patient monitoring system for monitoring the location of a patient at a distance, including a projector operable to project a pattern of light onto the surface of a patient and a imaging system operable to obtain images of a patient on to whom a pattern of light is projected. A heat sink is associated with the projector. A heat source, such as an array of resistors, is configured to apply heat to the heat sink when the projector is not being operated, reducing variation in the temperature of the heat sink which in turn reduces variation in thermal expansion and contraction of the monitoring system which can be a potential source of error for determining the position of a patient being monitored.

Abstract: Three camera rigs are connected by wiring to a computer. The computer is also connected to a treatment apparatus. A mechanical couch is provided as part of the treatment apparatus such that under the control of the computer the relative positions of the mechanical couch and the treatment apparatus may be varied. The camera rigs obtain video images of a patient lying on the mechanical couch the computer processes these images to generate a three-dimensional model of the surface of the patient which is utilized to position the patient relative to the treatment apparatus.
