Abstract
An imaging system for performing tomosynthesis on a region of an object comprises an x-ray source, motion controller, an x-ray detector and a processing unit. The x-ray source is positioned at a predetermined distance from the object and continuously moves along a linear path relative to the object. The x-ray source transmits x-ray radiation through the region of the object at a plurality of predetermined locations. The motion controller is coupled to the x-ray source and continuously moves the x-ray source along the path relative to the object. The x-ray source minimizes vibration in the imaging system due to continuous movement. The x-ray detector is positioned at a predetermined distance from the x-ray source and detects the x-ray radiation transmitted through the region of the object, thus acquiring x-ray image data representative of the region of the object. The processing unit is coupled to the x-ray detector for processing the x-ray image data into at least one tomosynthesis image of the region of the object.
