Computed tomography dose management practices and the adoption of automated dose monitoring tools in Australia: a national survey

This study investigates computed tomography (CT) dose management and automatic dose monitoring software (DMS) use in Australian radiology departments. An online survey covering departmental characteristics, dose management practices, DMS usage, and radiation protection activities was distributed through national radiation organisations and social media. Of the 132 initial responses received, 45 were eligible, completed, and analysed. The findings indicate 91% (n = 41/45) of departments regularly assess CT doses, with 63% (n = 26/41) conducting such assessments only once a year. Automatic DMS tools were utilised by 41% (n = 17/41) of these departments for CT dose data collection and analysis, while 59% (n = 24/41) relied on traditional methods. Only 25% (n = 6/24) of non-DMS users indicated plans for future adoption. A radiation protection team was present in 41% (n = 17/41) of departments. While dose assessment is commonly practised, it mostly relies on manual methods and is performed infrequently. Broader DMS implementation and formal radiation protection teams are recommended to strengthen CT dose management and enable continuous monitoring.
