Abstract
A tomosynthesis system for forming a three dimensional image of an object is provided. The system includes an X-ray source adapted to irradiate the object with a beam of X-rays from a plurality of positions in a sector, an X-ray detector positioned relative to the X-ray source to detect X-rays transmitted through the object and a processor which is adapted to generate a three dimensional image of the object based on X-rays detected by the detector. The detector is adapted to move relative to the object and/or the X-ray source is adapted to irradiate the object with the beam of X-rays such that the beam of X-rays follows in a non arc shaped path and/or a center of the beam of X-rays impinges substantially on the same location on the detector from different X-ray source positions in the sector.

54. A method of X-ray imaging a patient'"'"'s breast comprising:
-
disposing the breast between a digital detector and a compression paddle to position the breast between an X-ray source and the detector; and
imaging the breast with X-rays from the source that pass through the breast and impinge on the detector, from a number of different positions of the source and detector relative to the breast, to generate image data fro the respective positions;
wherein the detector is moved relative to the breast generally in a plane and the source is moved relative to the breast to direct radiation towards the detector from a number of source positions, including a position generally perpendicular to the detector and the paddle. - View Dependent Claims (55, 56, 57, 58, 59)
