Did you know .?.
CT scanning is a medical imaging technology; established in Britain in 1971 , it can now be found world-wide
This is the web site of the ImPACT CT scanner evaluation group.
ImPACT was the UK's CT scanner evaluation centre for 25 years. Their experts
provided a wide range of CT scanner related services to the NHS and other providers of healthcare; primarily in
the UK, but the knowledge and information has benefitted users and patients
around the world.
What is a CT scanner ?
A CT (or CAT) scanner
produces x-ray images of 'slices' through the body. See our patient's
guide for more information.
On this site, we give you an idea of the work undertaken by the group, as
well as providing ongoing access to some of our many resources for use by all
people involved in CT scanning.
Some of the most current topics and recent additions are listed below.

website updates
Due to the closure of the ImPACT group, this site is now only infrequently
updated and maintained. We are attempting to keep things up to date, but please
forgive the tardiness
broken links to reports - an update
We are aware that there were problems with the links from our site to the
archive of published reports. This was due to closure of PASA and the transfer
of their copywrite material. We have now updated our links and they should
work. However, there may still be issues arising as responsibility for
maintaining CEP reports passes from NHS PASA to the Department of Health. You
can now go to our report list and select the report
you want to download.
Apologies for any inconvenience that this may have caused you.
