The CT users group

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.

Fourth UK National CT dose survey

Public Health England have announced their intention to conduct their next review of doses from CT examinations in the UK in 2018. At this stage, they want assistance with deciding which examinations to include in the review, as well as to get an idea of the number of centres who are able to provide data, a short questionnaire has been developed.

The questionnaire can be accessed at the following link - and they would appreciate if you could take some time to complete it.

The survey will be open for one month, until the 7th July. More information on this and previous surveys at the CTUG dose survey page.

Last CTUG meeting: 19th October 2017

The last meeting of the CT Users Group was held on the 19th October 2017 at Bristol M Shed.

The meeting programme is available online, pdf versions of some of the presentations are available to download.

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!
