Use of a Human Visual System Model to Predict Observer Performance with CRT vs LCD Display of Images
TLDR
We evaluated a human visual system model based on just noticeable difference (JND) and frequency-channel vision-modeling principles to assess whether a Cathode ray tube (CRT) or a liquid crystal display (LCD) monochrome display monitor would yield better observer performance in radiographic interpretation.

Determining the MTF of Medical Imaging Displays Using Edge Techniques
TLDR
The modulation transfer function (MTF) of a medical imaging display is typically determined by measuring its response to square waves (bar patterns), white noise, and/or line stimuli. Expand
