Abstract
Digital Tomosynthesis (DT) is a type of limited angle tomography providing the benefits of 3D imaging. Much like Computerized Tomography (CT), DT allows greater detection of 3D structures by viewing one slice at a time. In contrast to CT, the DT projection dataset is incomplete, which violates the tomographic sufficiency conditions and results in limited angle artefacts in the reconstructed images. The present invention provides a method of producing a tomogram in which reconstruction is performed along lines on the x-ray detector paneldefined by a point on the detector panelclosest to a point location of the x-ray emitter, to a location of a respective pixel on the perimeter of the x-ray detector panel. In this way, artefact reduction is achieved, particularly at higher cone beam angles, and at lower stand-off distances.
