Patent ID: 8085897

Claim:
An X-ray imaging system for generating a three-dimensional image of an object that is positioned within an imaging volume having a central axis defined by a length comprising: a detector array comprising a plurality of rings of detector elements, wherein each of said plurality of rings encompasses a portion of said imaging volume, each of said plurality of rings has a length parallel to said central axis, and the length of the central axis is greater than the length of each one of said plurality of rings; and a stationary X-ray source comprising an anode with more than one source point, wherein the more than one source point are positioned behind said detector array relative to the imaging volume, wherein said detector elements detect X-rays which are from the more than one source point and which have passed through at least one slot in said detector array and into the imaging volume, wherein data from the detector array is used to produce said three dimensional image of said object within the imaging volume, and wherein a three dimensional image of the entire imaging volume is obtained without moving said object.
