摘要:
A mammographic imaging system is optimized for use with a single fixed size flat panel digital image receptor. It accommodates compression devices (paddles) of varying sizes, and positions them properly in the field of view of the image receptor. When a compression paddle with size smaller than the field of view of the image receptor is used, the compression paddle can be shifted laterally in the direction parallel to the chest wall, so as to facilitate different views of different size breasts, and permit the image receptor to image as much of the desired tissue as possible. An automatic x-ray collimator restricts the x-ray illumination of the breast in accordance with compression paddle size and location in the field of view. An anti-scatter grid, mounted inside the image receptor enclosure, just below the top cover of the enclosure, can be retracted out of the field of view of the image receptor for use in magnification imaging.

摘要:
A bend limiter/strain reliever is provided for maintaining optical fiber bend limits at exit portals of a optic fiber closure for the closure's entire range of motion, from being fully closed to being fully open. Bend limits are maintained as optical fiber is directed on paths through a closure exit portal between the closure interior and wire brackets on the closure exterior. Fibers are retained, organized and strain relieved by the bend limiter/strain reliever such that directed fiber is maintain at a minimum bend radius on such fiber paths. The curved surface of the bend limiter/strain reliever allows the closure to be accessed without excessive bending of so routed optical fibers. In this manner, optical signal degradation and/or total loss is avoided by limiting the bending of routed optical fiber to radii in excess of a predetermined minimum bend radius. Horizontal members separate the bend limiter/strain reliever into compartments and make it easy to isolate fibers so that they may be efficiently traced and removed during system maintenance.
