Facility reference level data
On the page:
The curves below show the cumulative distributions for the DLP and CTDIvol from adult DRL surveys submitted to ARPANSA between the end of April 2013 (when we started collecting information regarding iterative reconstruction) and the end of 2015. The plots display the percentage of surveys that achieved a facility reference level (FRL) below the dose specified on the x-axis.
The blue curve represents all of the submitted data, the green curve represents the surveys where iterative reconstruction (IR) was used and the red curve represents the surveys where IR was not used. The data portrayed includes data older than that used to calculate the current DRLs and, consequently, the DRLs do not match the 75th percentile of the plotted distributions.
Note that cervical spine, KUB and soft-tissue neck data are not included because the protocols have only been introduced recently.
