Conclusion
Teamplay™ provided a method for establishment of cardiac CT DRLs and KPIs.
In the absence of national DRL data for cardiac studies,
it is useful to have the global data base to benchmark these studies against.
However care should be taken when comparing global data as mapping and identification of studies can be problematic.
It was found that mapping of protocols was complex and involved both the scanner and the local PACS resulting in incorrect mapping of some procedures.
Filtering by body region was found to be problematic as similar exam protocols were listed under different body parts.
For example,
cardiac studies can be found under both Heart and Chest body regions.
There are limitations with the system such as the absence of patient weight data.
Although not fully relevant to this paper,
of note there is no facility for the calculation of organ dose which is available on some dose management systems. Teamplay™ enables efficient analysis of CT dose data,
allowing DRLs to be evaluated on a more frequent basis and also contributes to the optimisation of studies.
