Abstract:
1. A system selectively operable in each of a tomosynthesis mode and a mammography mode, comprising: an x-ray tube, an x-ray imaging receptor, and a breast immobilizer, wherein (i) the x-ray tube and x-ray imaging receptor are decoupled from the breast immobilizer when the system is operating in said tomosynthesis mode but (ii) the tube, receptor and immobilizer are mounted to move as a unit between different mammography imaging positions when the system is operating in said mammography mode; and an anti-scatter grid mounted between the breast immobilizer and the x-ray imaging receptor; said anti-scatter grid remaining between the source and the receptor to suppress x-ray scatter both when the system is operating in said mammography mode and when the system is operating in said tomosynthesis mode; said system being configured to operate selectively in:
