Multi-source inverse geometry CT(MS-IGCT) system: A new concept of 3D CT imaging

Abstract

Third-generation CT architectures are approaching fundamental limits. While alternative architectures such as electron beam CT and dual energy CT has been proposed, they have severe tradeoffs in terms of image quality, dose-efficiency, and complexity. In this work, we present the concept of multi-source inverse-geometry CT(MS-IGCT) system which overcomes several limits of current CT architectures, and The 3D reconstruction algorithm and initial experimental results of the MS-IGCT system are also presented.
