Abstract:

A breast compression plate is connected to a cartridge sleeve for containing a mammographic film cartridge with adjustable tension in a range of positions with detachable straps. The plate is a semi-rigid planar member having a plurality of perforations disposed in a matrix for locating a needle used to determine the position of breast lesions. The plate has spaced buckles which are secured to the straps. The straps have a series of loops formed on one side which are gripped by a plurality of closely spaced hooks secured to spaced ends of the cartridge sleeve. The series of loops extend along the length of the straps to permit changing the length of the straps extending between the plate and the cartridge sleeve, thereby permitting lateral positioning and tension adjustment. The plurality of hooks extend across the cartridge sleeve generally perpendicular to the length of the straps on opposite ends of the sleeve to permit positioning of the plate perpendicularly relative to the length of the straps.
