Uvjeti očitavanja radioloških snimki u četiri zdravstvene ustanove

Diagnostic monitors as well as ambient illumination in the reading rooms must meet the minimum prescribed requirements. Recommendations regarding diagnostic monitors as well as ambient illumination can be found in several international recommendations. The aim of this study is to show the results of the investigation carried out in four healthcare institutions in Republic of Croatia in which 114 monitors of twenty different manufacturers are used for readings of radiographic images. 45 % of those monitors were diagnostic monitors, 12% diagnostic monitors dedicated to mammography while 25 % of them were COTS (commercial off-the-shelf) monitors and 18 % were medical monitors which were originally used as reviewing monitors. Six recommended and four prescribed parameters were tested and it was found that 51 % of tested monitors met the prescribed requirements for selected parameters and only 46 % for the minimum recommended requirements. Only 29 % of diagnostic monitors dedicated to mammography met recommendations given for this type of monitors. None of COTS monitors met all selected prescribed and recommended requirements. The ambient illumination in reading rooms ranged from several lux to several hundred lux, depending on the type of light source and often depends on the time of day and the weather conditions. Results of this study indicate the need for paying more attention to the selection of monitors which will be used as diagnostic monitors and to their regular testing and calibration as well as to the reading rooms where these monitors will be used.
