In this work we evaluate the quality of display devices - monitors and negatoscopes - radiological medical images, as well as the lighting of the rooms report of a group of seven hospitals - School of Northeastern Brazil, distributed by Northeastern capitals of five states . The data shows serious problems in terms of display and visualization of these hospitals. The valuation of these items reflects directly in providing a correct medical diagnosis. Parameters evaluated in digital displays, proposed by the American Association of Physicists in Medicine were the geometric distortion, reflection, luminance, luminance uniformity, resolution, noise and glare. The negatoscopes were evaluated following the recommendations of Spanish Protocol of Quality Control of the 2002, the American College of Radiology and the Ministry of Health (ANVISA). We investigated the luminance of negatoscopes from general radiology and mammography, which must present acceptable limits of operation as well as the illuminance of rooms report that may interfere with the outcome of the report. We note here that a considerable part of the devices analyzed are at odds with protocololos quality control, thus demonstrating a serious public health problems in the northeast.
