Poster Presentations - Imaging Technologies and Informatics

Abstract

The purpose of the 2017 Conference was to review actions taken and developments since the 2012 Bonn conference, especially focusing on actions taken by all relevant parties in line with the Bonn Call-for-Action. This will enable review of the overall approach to implementation of these actions and harmonization of activities between international organizations and other stakeholders, as well as allowing stakeholders to look ahead at new developments impacting on radiation protection in medicine. Whilst the medical benefits of the use of ionizing radiation in medicine are unquestionable, there is growing evidence of unintended and unnecessary use of radiation in medicine. The conference dealt with justification and optimization in medical exposure; safety in medical use of ionizing radiation; and radiation protection of medical staff and public when ionizing radiation is used for diagnosis, intervention, therapy or research. The 2017 conference was attended by 534 participants from 97 countries. Invited papers from authorities in the field were supplemented by approximately 200 contributed papers and 80 posters. This presentation will outline the structure of the 2017 Conference, and offer a summary of key points. IMAGING TECHNOLOGIES & INFORMATICS P153 An investigation into the impact of aging on the performance of LCD 2.4 MP colour display monitor when visualising low contrast detail using a CDRAD phantom Sadeq Al-Murshedi; Peter Hogg; khouloud Alzyoud; Andrew England Salford University Background: To Investigate the influence of deterioration of 2.4MP LCD colour display monitor luminance as a result of the longterm use on its performance in visualising low contrast details with different image quality. Method: A 2.4 MP LCD colour display monitor was set at three different maximum luminance values (250, 140, and 116 cd/m2) to simulate the monitor in initial use, after 1 year and after 4.6 years. This was based on the monitor being used 24/7. Six CDRAD images were generated using adults chest radiography protocols with different levels of image quality. The images were assessed on the monitor by four observers in three different sessions with the three different levels of luminance to investigate its influence on image scoring. Results: Data analysis was conducted via repeated measures of variance (ANOVA). The overall ANOVA has shown that there is no significant difference (p=0.30) between the three ages (the three levels of luminance) of the monitor. Furthermore, the pairwise comparisons between the mean scores of monitor in initial use with that of the other two ages have shown that there is no significant difference among them p=1.00 and p=1.00 respectively. Conclusion: The study shows that the monitor aging has no significant influence on its performance for detection of low contrast details and the monitor can be used for clinical practice without needing to be replaced.
