A major issue in telepathology is the extremely large and growing size of digitized "virtual" slides, which can require several gigabytes of storage and cause significant delays in data transmission for remote image interpretation and interactive vis

Rationale and Objectives As liquid crystal displays (LCDs) age, the whitepoint shifts toward a yellow hue, changing the appearance of the displayed images. This study examined whether this shift in whitepoint influences observer performance and visua

Full-field digital mammography (FFDM) systems are currently being used to acquire mammograms in digital format, but digital displays are less than ideal compared to traditional film-screen display. Certain physical properties of softcopy displays [e.

Rationale and Objectives Although cathode-ray tube (CRT) displays typically are used for softcopy display of radiographs in the digital reading environment, liquid crystal displays (LCDs) currently are being used as an alternative. LCDs have many des

Results of physical as well as psychophysical evaluation of an LCD with respect to its spatial noise are presented. Spatial noise is determined using a high-resolution CCD camera and a method is developed to compensate for it. This compensation algor
