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: 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.
CTUG training course: 5th October 2022
The day before the 2022 meeting, we ran our first one-day training course - described as “An introduction to the physics of computed tomography, including how images are produced and factors affecting radiation dose and image quality”, check out the CTUG training course page for more details. We are planning to run this course again prior to the 2024 meeting.
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.
IQWorks - automated image analysis software for medical physicists
As part of an ongoing interest in automated analysis of CT (and other digital modality) images, CTUG is proud to be involved with the development and support of IQWorks.
This project aims to build on the fantastic work by Andrew Reilly as part of his PhD research at Edinburgh University. The software can now be downloaded, and broader input into its development as an open source project is encouraged. Follow the link above to find out more!
