Abstract
We investigated the link between the results from daily quality control (QC) data, on the one hand, and from successive half-yearly medical physics QC visits on the other hand. To do so, criteria defining ‘unchanged results’ were set for both the daily QC data and the half-yearly QC results. Out of the results of 181 QC visits and daily QC at the time of the QC visit, we found that systems that showed little or no deviation in daily constancy performance were likely to show basically unchanged results in the half-yearly medical physics test. The specificity of the daily QC data for a change in results at QC visits was 93% for the dose and SDNR test and 88% for a change in contrast threshold values. Daily QC data could be used to prioritize the work load of the medical physicist.
