Friday 12th December saw the last meeting of the year organised by IPEM’s DRSIG held in the Manchester Conference Centre. Organised by DRSIG member Tim Wood, the conference was to highlight where a potential future version of IPEM 91 should go and what type of testing should it include.
It was only fitting that one of the authors of report 91 should launch the day; Peter Hiles gave a brief history of where report 91 came from but then started a discussion with a suggestion that task-based QA would be more appropriate, and even flexible/dynamic frequency of testing should be considered. There was agreement in a talk by Ronan Faulkner who showed evidence of QA results passing yet either patient doses were high or image quality for a given task not acceptable by radiologists.
The morning was completed with three different talks on evidence based QA, the first from the IPEM Evidence Based QA Working party, given by Ian Honey, showing the results so far on tube and generator testing and a flavour of AEC results. Aoife Gallagher gave some very similar results in the Irish equivalent study while Kevin Munson showed a different approach, taking an engineering view with Failure Modes, Effects and Criticality Analysis.
Overall the morning put a strong argument forward that future QA should focus, not on how a system creates an image but on whether that image is adequate for the task and comes at a dose that is ALARP.
The afternoon looked at some specific items that people are testing locally, starting with work by Craig Moore investigating some image quality metrics in chest radiography while Kostas Michael looked at some quantitative image analysis on digital detectors. Greg Stevens then gave an overview of some items that are not always included in QA programmes but could be essential before IRS’s own Paul Charnock gave a talk on his experiences in attempting QA on Dexa.
The final session was more of the same with Christie Theodorakou giving a talk about her experiences with dental CBCT and Debbie Saunders explaining how she has attempted to use report 91 to put a QA programme for radiotherapy linac kV imaging systems. The final talk of the day was left to Gareth Iball who proposed a level A QA test for CT AEC systems.
The afternoon showed a good snapshot of how the community has adapted the principles of report 91 to newer technology. All in all, the conference was very good with plenty of discussion regarding current QA issues and what needs to be considered going forward.
