Abstract: The housing for a breast imaging system contains an x-ray source and is configured to rotate relative to the breast. The housing for an x-ray receptor has a breast support platform and extends from an arm assembly which rotates independently from the x-ray source housing. A compression arm assembly connected to the arm assembly moves between a first linear position proximate the x-ray receptor housing and a second linear position distal the x-ray receptor housing. A pair of extension arms are pivotably connected to a strut which removably secures a compression paddle to the compression arm assembly substrate. The extension arms move between a first pivoted position substantially aligned with the strut and a second pivoted position disposed at an angle to the strut.

Abstract: A multi-mode system and method for imaging a patient's breast with x-rays in one or more of a CT mode, a narrow-angle tomosynthesis mode, a wide angle tomosynthesis mode, and a mammography mode, using essentially the same equipment, on one or more compressions or immobilizations of the breast.

Abstract: In a tomosynthesis system a static focal spot is moved in a direction opposite to and generally synchronized with the directional movement of an x-ray source and X-ray collimator blades are moved during each exposure in synchronization with the shifting of the static focal spot. The synchronized movement of the static focal spot, x-ray tube and collimator blades helps keep the effective focal spot fixed in space relative to the breast, detector or both during the entire duration of the exposure and keeps the x-ray field on the detector and breast static. The shifting collimator blades follow an oscillating pattern over the multiple x-ray exposures of a tomosynthesis scan.
