MODULAR FIXED BEAM-LIMITING DEVICE FOR INTRAORAL X-RAY SYSTEM

摘要

A modular beam-limiting device (17) for use with an x-ray machine (15) includes a base portion (30) and an attachment portion (32). The base portion (30) includes at least one magnet (36). The attachment portion (32) includes at least one magnet (36). The base portion (30) is adapted to be received on an x-ray tubehead housing (28). The attachment portion (32) is selectively removably couplable to said base portion (30). The modular beam-limiting device (17) may further include a magnetic field modulator (40), which is operable to shape a magnetic field; an insert for configuring a size, a shape, or an orientation of an aperture of the beam-limiting device (17); or an adapter for increasing an axial length of the beam-limiting device (17).
