Luminance Characteristics of Cathode Ray Tube (CRT) Monitors in Cineradiographic Systems

Luminance artifacts of cathode-ray tube displays for vision research.

Phosphor persistence, video bandwidth, DC restoration and high-voltage regulation affect the appearance of images presented on cathode-ray tubes (CRTs), potentially resulting in differences between nominal and actual stimuli. We illustrate these effects by measuring physical parameters of horizontal and vertical static and counter-phase flickering gratings, and we illustrate problems for vision...

Cathode Ray Tube (crt) Lead Glass: Lead Leaching Study after a Chelating Agent Treatment

This study is focused on the removal of leachable lead present in CRT (cathode ray tube) glass employing different chelating agents, NTA (nitrilotriacetic acid) and ATMP (amino trimetilen phosphonic acid), and then on the evaluation of their extractive capability. The operating conditions are the following: T=80°C, t=1h, pH=10, solid/liquid weight ratio=1/10, reagent concentration= 0.1 M. After...

Modeling the effects of gamma on the colors displayed on cathode ray tube monitors

The Channel Multiplier Cathode-ray Tube

This paper describes a new approach to cathode-ray tube design aimed at achieving a significant depth reduction. The addressing function of the electron beam has been separated from the light generation process by a channel electron multiplier array, allowing the use of a novel deflection system based on a low-power scanning beam. Monochrome versions of the thin tube have been made with a 12" (...

Liquid-Crystal Display Monitors and Cathode-Ray Tube Monitors: A Comparison of Observer Performance in the Detection of Small Solitary Pulmonary Nodules

OBJECTIVE To compare observer performance using liquid-crystal display (LCD) and cathode-ray tube (CRT) monitors in the interpretation of soft-copy chest radiographs for the detection of small solitary pulmonary nodules. MATERIALS AND METHODS By reviewing our Medical Center's radiologic information system, the eight radiologists participating in this study (three board-certified and five resi...
