will provide information on the level of fundamental image quality variation present at 27 international lung cancer screening sites and the potential impact of this variation on CT lung nodule measurement performance. The clinical sites participated in a first-of-its-kind crowd-sourced image quality study based on CT scanning and analysis of three rolls of 3M Scotch tape. More information on the presentation and the conference will be available at the World Congress of Thoracic Imaging website.

objects, demonstrated using rolls of 3M Scotch Tape, can be used to efficiently monitor the performance of global CT scanners and imaging protocols. More information on the presentation and the conference can be found on the Dialog For Action website

in May and June of 2016, was the first crowd-sourced and ultra-low cost study to help the lung cancer and COPD imaging research communities determine the best CT scanners and protocols for the detection and measurement of lung cancer and COPD. Within the two month data collection period the study obtained CT image quality data from 27 healthcare institutions, 54 CT scanners, and 130 individual CT scans. This first of its kind study data is now helping shape imaging protocol recommendations for lung cancer screening and COPD. The challenge results and potential implications for globally improving the quality of future population screening initiatives will be presented.
