Image quality is resilient against tube voltage variations in post-mortem skeletal radiography with a digital flat-panel detector

Abstract In recent phantom studies low-contrast detectability was shown to be independent from variations in tube voltage in digital radiography (DR) systems. To investigate the transferability to a clinical setting, the lower extremities of human cadavers were exposed at constant detector doses wit...
