Abstract

Three-dimensional image information is generated of a body part that is larger than the visual field of an X-ray machine. An X-ray source and an X-ray detector are disposed at a first position such that the X-ray source and the X-ray detector can record a first projection image of at least a first section of a body part. Then the first projection image is recorded. The X-ray source and the X-ray detector are next disposed at a second position such that the X-ray source and the X-ray detector can record a second projection image of at least a second section of the body part. The second section partially overlaps the first section. The first and second projection images are merged to form a projected image. A three-dimensional volume of the body part is reconstructed from the plurality of projection images.
