PROBLEM TO BE SOLVED: To provide a tomosymthesis imaging technology that does not need to match the X-ray focal position and the center line of the field of view of a detector with the center of the imaged object, in view of the system cost or system speed. SOLUTION: The present invention is directed to an apparatus and method for acquiring off-axis X-ray images of a plurality of regions of interest. The apparatus includes a source 112 producing a beam of radiation, a surface 120 to support a subset of the plurality of regions of interest A, B and C, and an X-ray detector 130 located to simultaneously receive portions of the beam that have passed through the subset of the plurality of regions of interest. The X-ray detector produces from the received portions of the beam an electronic representation of an image for each region of interest in the subset of the plurality or regions of interest. Any combination of the radiation source, the support surface, and the detector may be moveable to position the regions of interest within the beam. COPYRIGHT: (C)2007,JPO&INPIT |
