Abstract: An optical imaging system for interfacing with a separate examination apparatus and methods of making and using the same are disclosed. The optical imaging system can include an imaging housing including a housing enclosure and a housing receptor plate, a subject support mount, a cart including an extendable arm, an optical arrangement including an optical source, a cantilever mirror system, and the housing enclosure, and a detection optical path providing optical communication between the cantilever mirror system and an optical detector. The subject support mount allows optical illumination via at least one optical port. The extendable arm is affixed to the cart at one end and the optical arrangement at another end. The extendable arm can move from a retracted position to an extended position without contacting the subject support mount or the subject.

Abstract: For the delivery of high precision radiation treatment, the accuracy with which a target is irradiated at individual gantry, collimator and patient couch orientation is traditionally verified in 2D. With the QA device described herein, the coverage of the gantry is uniquely measured in 3D. The method of the present invention, combining with the collimator and patient couch measurements, allows the reconstruction of the target coverage in full 3D, which was not possible before. In addition, the method of the present invention can be applied to decompose the traditional quality assurance measurements of combined gantry, collimator and patient couch orientations with standard devices. Such an application provides a comprehensive description of the irradiation accuracy.
