The Spectra-Cine Candela IIIR PhoRad Luminance Photometer accurately and consistently measures the light output of radiological equipment (viewing boxes, image workstation monitors, image intensifier monitors) to ensure that user is in compliance with recommended light levels.
Why is this so critically important? In an effort to reduce the rate of misdiagnosis (estimated to be as high as 30% by a number of research studies), the Federal Drug Administration, American College of Radiology (ACR), the American Cancer Society and the European community of radiologists have all adopted guidelines and standards for viewing lighting levels. Readings from the highly accurate and consistent Candela SC-810 PhoRad IIIR luminance Photometer are in nits or candelas per meter squared (cd/m2) or foot Lamberts (fl).
This instrument is highly recommended for quality assurance and consistency of medical imaging at Diagnostic Imaging departments in hospitals and clinics.
Note: Nit: an MKS unit of luminance, equal to one candela per square meter, or 10-4 stilb. The nit is not approved as part of the SI, but it has been approved since 1947 by the International Commission on Illumination (CIE) and is in wide use. The name of the unit comes from the Latin niteo, to shine. This unit is sometimes called the meterlambert, by analogy with the footlambert.
Spectra Candela PhoRad IIIR Photometer model SC-810 is essential for quality assurance of medical imaging at Diagnostic Imaging departments in hospitals and clinics
Specifically designed to measure light intensity of viewing port, viewers, image monitors and etc., directly in candelas per meter squared (cd/m2) as set forth in the standards outlined in the Standard Practice for Radiographic Examination; Measures both display device luminance and ambient illuminance
Measures the viewing room ambient background illumination falling on the viewer surface as set forth in industry standards
