Image quality in medical x-ray imaging is dependent on the characteristics of the x-ray photons produced by the x-ray tube, the detection of the x-ray photons in the detector and the image processing. X-ray image guidance during endovascular interventions is usually performed with C-arm fluoroscopy. It is of major importance that the image quality is sufficient for the procedure. The understanding of what affects the image quality could be made easier if the performance of the different parts of the system were to be judged separately, rather than considering the system as a whole. The term Image QualityTube Output that is used throughout this thesis describes the image quality that only depends on the characteristics of t...
