SYSTEMS AND METHODS FOR POSITIONING PATIENTS DURING TARGET TRACKING IN RADIATION THERAPY AND OTHER APPLICATIONS

摘要

One embodiment of such a system comprises a sensor assembly mounted in a fixed location relative to a machine isocenter. According to another embodiment, the sensor assembly includes a fixed mounting bracket and an articulating arm allowing movement of the sensor assembly while allowing translation of the sensor assembly location with reference to the machine isocenter According to still another embodiment, the sensor assembly is positioned in a fixed relationship relative to the patient support assembly, mounted below the patient support assembly, as an overlay on the patient support assembly or integral to and forming a portion of the patient support assembly. The sensor assembly location is referenced to the machine isocenter through the relation of the table to the machine isocenter or through an independent locating system for the sensor assembly. According to yet another embodiment, the sensor assembly is located relative to machine isocenter by conventional imaging techniques.
