Paper Abstract

An evaluation was performed to characterize a new digital imaging system, the System One, DigiRad, Inc. and its image processing capabilities. This evaluation included reproducibility, dynamic range, linearity and the effects on several image recording system. Results show that the System One dynamic range is limited to 1300 levels in the range of 0.0 to 2.8 optical density units. It was observed that within this range, the System One response was approximately linear and reproducible within -1%. The system spatial resolution limit is between 3.0 and 3.5 1p/mm. All processing algorithms applied to digitized images of bar pattern film images degraded the resolution as compared to the images with no post processing. Improvements in System One are expected and will be evaluated as soon as they are available.
