Welcome to the CT Users Group web site

We are a UK based group for people with an interest in medical CT scanning. Our main aim is to share experience and knowledge relating to CT scanning with each other, as well as to provide an educational forum. We formed in 1999, and are mainly hospital physicists, but we also count radiographers and radiologists amongst our number.

Our primary interactions are via our meetings, usually held once a year. These are held in locations all round the UK and are a great way to share knowledge, research work, projects and questions in an informal setting. Our mail list aims to continue the interaction from the meetings throughout the year by bringing conversation about CT via email.

More than 200 people from all over the world are now involved with the group - if you want any more details or are interested in joining, please contact us or subscribe to the mail list.

Last CTUG meeting: Friday 18th October 2024 in Exeter

The most recent CTUG meeting was held in Exeter on 18th October 2024. The programme is available on the meeting page, along with pdfs of the presentations.

The meeting was preceded on Thursday 17th October by the second CTUG training course, at the same venue, following a similar programme to the last training meeting in 2022.

CTUG training course: Thursday 17th October 2024 in Exeter

Our second one-day training course ran the day before the 2024 meeting. The course was an introduction to the physics of CT, covering a wide range of topics with Physicist and Radiographer representation. It was designed to be open to anyone, but to be particularly useful for trainee Technicians and Physicists (STP, route two etc) or those wanting a CT theory refresher. Check out the CTUG training course page for the programme, we expect to run this course again in 2026.

UK Paediatric CT dose survey

The IPEM paediatric optimisation working party, in collaboration with PHE, launched a UK paediatric CT dose survey in June 2019.

Further details, along with the spreadsheet for dose data entry and guidance on what information is needed can be found on the CTUG dose survey page.

Fourth UK National CT dose survey

Public Health England announced on 23rd March 2019 their next review of doses from CT examinations in the UK. This survey aims to collect protocol and patient dose index data for adult CT examinations.

Further details, along with the spreadsheet for dose data entry and guidance on what information is needed can be found on the CTUG dose survey page.

Data submission is open until the end of July 2019. If it is considered that insufficient data has been received for any examination at this time, this will be extended. It is the intention that participating centres will be (optionally) acknowledged in the final report.
