Meier, M. Fiebich] Increasing numbers of images in radiology and nuclear medicine are digital images. Various methods for quality analysis in digital imaging are studied. Images from two different digital luminescence systems and a computer tomograph are analysed by testing signal-to-noise ratio, modulation transfer function and Wiener spectra. The influence of different analytical methods is also described. The reproducibility of the measurements under specified conditions and analytical methods is shown. The results vary over a wide range and demonstrate the need for standardised experimental set-up and numeric analysis. Comparability of methodologies is important for determining and improving image quality in digital imaging, especially in view of patient dose reduction.
