Full field digital tomosynthesis method and apparatus |
摘要 |
A tomosynthesis system (1) for forming a three dimensional image of an object (2) is provided. The system includes an X-ray source (11) adapted to irradiate the object (2) with a beam (3) of X-rays from a plurality of positions in a sector, an X-ray detector (13) positioned relative to the X-ray source to detect X-rays transmitted through the object and a processor (21) 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 (7) 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. <IMAGE> |
