Abstract:
1. A radiation field detection system for use with a radiating device, the detection system comprising: a radiation detector configured to receive radiation and to provide radiation strength indicia of amounts of radiation received; a positioning mechanism connected to the radiation detector and configured to physically move the radiation detector; a processor coupled to the positioning mechanism and coupled to the radiation detector to receive the radiation strength indicia, the processor being configured to: an output port configured to be coupled to a controller that determines an excitation arrangement for the radiating device, wherein the processor is further configured to provide an indication of the first relationship to the output port for conveyance to the controller; wherein the second location of maximum radiation is one of (1) an expected location of maximum radiation and (2) a determined location of maximum radiation detected under a second radiation condition that is different than a first radiation condition in effect when the radiation was detected leading to the determination of the first location; and wherein the second radiation condition is a different angle of application of radiation by the radiating device, with the radiating device being a linear accelerator.
