DIRECTED ENERGY BEAM WELDED CT DETECTOR COLLIMATORS

摘要

One embodiment of the present invention is a method for constructing a post-patient collimator for a computed tomographic (CT) imaging system, the method including steps of: edge welding collimator plates to a top rail using at least one directed energy beam welder; and edge welding the collimator plates to a bottom rail, using the at least one directed energy beam welder. The above described embodiment provides an efficient and less expensive method for manufacturing a post-patient collimator for a CT imaging system than embodiments requiring use of precision combs for accurately positioning the plates.
