An integral component of a proton therapy system (PTS) composed of several elements (e.g., a collimator and scattering mechanisms) that permit shaping or scanning of the proton beam, typically using techniques such as double scattering, single scattering, u...
A standard, diagnostic x-ray beam-limiting and shaping device that includes an automatically controlled motorized shutter mechanism. It is designed to adjust the shutters so that the x-ray beam shape matches the size of the film cassette in the holder and i...
A non-motorized, x-ray beam-limiting and shaping device that is a component of a therapeutic x-ray system and that is adjusted manually. It is attached to the x-ray tube housing assembly and adjusts the size and shape of the x-ray beam to match the size and...
A standard, diagnostic x-ray beam-limiting and shaping device with a motorized shutter/length adjustment mechanism that requires the operator to manually adjust the collimator shutters or length of the cone prior to an exposure in order to match the size an...
