A New CT Construction System Suitable for Micro- and Macro-Focal Beam Guides Using a Multitarget System

Abstract

The goal of this study is the improvement of CT constructions by exploiting the Bremsstrahlung created by multitarget systems allowing additional focusing influences by suitable magnetic fields and small-angle scatter of the walls (preferably tungsten). The number of layers of these configurations can be restricted to 10 – 15 layers, if electron voltages are of the order 120 keV – 180 keV, depending on the kind of application (medical CT or CT in the technical/research field). The theoretical results very satisfactorily agree with Monte-Carlo calculations using GEANT4.
