Abstract

Introduction: Monitor specification and viewing conditions are important factors affecting image assessment in mammography. This survey evaluates the different viewing conditions and monitor specifications that exist in acquisition and reporting rooms in UK breast screening units. Methods: Static (n=10) and mobile (n=2) breast screening units were evaluated in North West England. Room illumination levels were measured in 3 locations for each room using a calibrated Lux meter and the specification of 122 monitors recorded. Room layout, wall colour, location and number of doors, windows and light sources were recorded. Results: In reporting rooms, 90/91 of monitors had similar technical specifications and were compliant to guidelines. The ambient light levels ranged from 10-25.8 lux. The mean illuminance was 12.32 ± 4.6 lux. In acquisition rooms, great variances appeared in monitor specification and ambient light levels. The majority of monitors (24/34) had 3 megapixel (MB) optimum resolution but the ambient light level ranged from 10-1020 lux. The mean illuminance was 105.3 ± 178.8 lux. The mobile units were consistent with each other and compliant with guidelines. Conclusion: A lack of consistency and great variances appeared in terms of ambient light levels and monitor specifications in the image acquisition rooms. However, there was excellent consistency among the illumination measurements and the monitors’ technical specifications in the reporting rooms. Implications for practice: This research demonstrates, for the first time, the need for further research and specialised guidelines for acquisition rooms.
