Multi-plate volumetric CT scanner gap compensation method and apparatus



Multi-plate volumetric CT scanner gap compensation method and apparatus



Official Gazette of the United States Patent & Trademark Office Patents 1258(2), May 14



A method and apparatus for configuring a large CT detector using a plurality of smaller X-ray type detector panels wherein the panels are sized and arranged in side by side fashion to extend across a fan beam and so that where conjugate rays generated during acquisition always include at least one ray that subtends a detector panel and generates a collected signal even where the other ray in the conjugate pair is directed at a gap between panels, the method further including, after data is acquired, interpolating across each gap and then combining the interpolated data across the gaps with the collected signals to generate back projection data for each of the gap directed rays.
