Paper Abstract

Gaseous detectors are excellent candidates for x-ray imaging devices which are suitable in the energy range between 5 and 90 kV. Especially the extreme low inherent noise floor which in principle is limited by the read out electronics only in combination with the high flexibility in the choice of gases and the geometry result in high detective quantum efficiency values (DQE). A DQE close to one is valuable especially in medical imaging applications where in general the image quality is dose limited. Moreover, recent developments in gas amplification structures such as the Micro-CAT allow fast imaging with a single photon precision also for integrating devices resulting in high DQE values even for low photon flux applications.
