Paper Abstract

Tomosynthesis, an imaging mode related to classical tomography, is designed to produce arbitrarily many tomograms through processing of an appropriate set of radiographs. This paper examines the applicability of digital radiography technology to this technique. In this approach, component radiographs are recorded using efficient detectors and stored directly onto disk memory whereupon tomograms are synthesized under flexible software control and displayed on a CRT. Digital image processing is easily performed to enhance these images. Experiments were conducted by operating a third generation CT scanner in the scanned projection mode. This paper gives an analysis of tomography using traditional geometries and extends it to deal with the fan-beam geometry. Experimental results are also shown.
