In this paper presampled modulation transfer function of the 2D images obtained on the Phoenix Nanotom scanner was investigated with different measurement set-ups. Three parameters were chosen to investigate their influence on modulation transfer function: source- detector distance, tube current and binning mode. A simple method for modulation transfer function determination of digital imaging detectors from edge images was applied. The following results were achieved and briefly discussed: modulation transfer function improves with increase of the source-detector distance, slightly improves with increase of the current and remains constant for different binning modes. All measurements were carried out in University of Applied Sciences Upper Austria at Wels campus.
