The purpose of this study was to investigate the quality of displays at radiology departments and\nhealthcare centers, viewing conditions, quality control practices and user experiences of viewing\nradiological images from displays during 2007. The study aimed to provide guidelines to\nimproving the quality of image viewing from displays and viewing conditions in healthcare.\nThe data was gathered from radiology departments at university hospitals in Finland and\nhealthcare centers in the treatment area of responsibility of the Oulu University Hospital. Display\ntechnology, quality control practices and users experiences of viewing were determined using\nquestionnaires. Technical measurements were performed in order to acquire information on\ndisplays performance and viewing conditions. In addition, observation was used to evaluate\nviewing conditions.\nAlmost all displays at radiological departments were applicable for diagnostics. At healthcare\ncenters all displays were inapplicable for diagnostics. Both organization groups had displays using\nobsolete cathode ray tube technology and these displays did not pass current acceptance criteria.\nMost radiology departments had viewing conditions which were compatible with existing\nguidelines, whereas at healthcare centers lighting conditions were too bright for viewing\nradiological images from displays. Acceptance testing was done only for few of the displays and\nquality control was not performed regularly. Personnel responsible for quality assurance felt they\nwere provided with inadequate resources for performing display quality control. Clinicians at\nhealthcare centers did not identify the poor performance of displays. Radiologists and clinicians\nat healthcare centers rarely performed quality assurance for displays.\nThe quality of displays, viewing conditions and the assessment of display performance at\nhealthcare organizations was not at the level required by the existing guidelines. Both the cathode\nray tube displays and uncalibrated liquid crystal displays should either be replaced with new ones\nor calibrated. Lighting and positioning of displays ought to be rearranged in order to diminish\nreflections. Furthermore, doctors ought to be able to rearrange lighting conditions with ease. More\nresources ought to be directed to display quality control and different quality control practices\nshould be unified. Both the users and the quality control personnel should also be provided with\nmore training in display quality control. Regular display quality control should be extended to all\nhealthcare organizations. Clinicians working at healthcare centers should be provided with\nadequate training in the use of image viewing software.
