Methods for characterization of digital, image-producing detectors within medical X-ray diagnostics

Abstract: Construct a test object (phantom) that can generate a sharp edge in the X- ray image. Develop a program code in the high-level language MATLAB for determination of earlier mentioned parameters, MTF and DQE in particular. Work out radiation geometry, suitable for the purpose. Verify the usability through practical measurements on already existing clinical equipment at the hospital in Blekinge. Study the effect of radiation energy, dose of radiation, detector direction, spatial frequency, variation of sampling of the edge spread function (ESF), etc. Compare gained results with relevant literature. The practical meaning of the present case project is to: Make a clinically usable method for the quality safety of digital, medical X- ray equipment available at the hospital in Blekinge. Transfer, from the hospital in Blekinge to the Blekinge Institute of Technology, competence within medical radiation physics and medical technology, which could be interesting since the University is considering increasing their commitment within this area. The method can be spread within the informal co-operation, concerning medical radiation physics that is present within the hospitals outside the University districts in the southern region.
