Abstract

A 10-12 bit gray scale is provided in commercial laser film digitizers. The true contrast resolution on the digitized image within 200 microns square is limited by both the quantum mottle and instrumentation noise. In this paper, we investigate that mean value, standard deviation, and adjacent pixel correlation coefficient on a calibrated step wedge film with two laser digitizers. The results were disappointing. On the output side, the brightness of different grey levels from a clinical monitor was measured with a narrow angle luminance probe. In addition, the imlipcations for teleradiology applications are discussed in this paper.
