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.

Next CTUG meeting: Friday 18th October 2024 in Exeter

The next CTUG meeting will be in Exeter, at the Mercure Rougemont Hotel, which is in the city centre and within walking distance from Exeter St Davids and Exeter central train stations. The programme is now almost finalised, and registration is open. Check the meeting page for details.

The meeting will be 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 will run the day before the 2024 meeting. The course will be an introduction to the physics of CT, covering a wide range of topics with Physicist and Radiographer representation. It is open to anyone but may 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 programme and registration details.

Last CTUG meeting: 19th October 2023, Cardiff

The last meeting of the CT Users Group was on the 19th October 2023 in Cardiff - check out the meeting page for more details of the programme and links to the presentations.

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.
