3D CT Imaging

We have been developing 3D imaging techniques for about 15 years, using hardware and software developed here at UCL and UCL Hospitals. This page focuses on some of the methods which have proved of considerable value and interest using X-ray CT (Computed Tomography).  These techniques were made possible by the use of a 3D workstation with facilities for rapid processing and a range of sophisticated interactive facilities. First some hard tissue images (bone) then soft tissues.

Skull This image shows a skull requiring a cranioplasty to cover the defect. We manufacture anatomical models and titanium cranioplasty plates as one of our routine NHS services (images can come via the internet but the manufactured plates still need to be sent by post).
Skull This image shows how image 'surgery' can be applied, in this case separating and moving the mandible.

carnation Hard tissue surfaces are usually straightforward to render in 3D. However for soft tissues we need to be able to see inside. This study of a  carnation which had been given an iodine contrast agent shows the surface rendered in gold and the internal structures as a normal CT greyscale where the (imaging) cuts have been applied. 
( No abnormality was found and the subject was asymptomatic after 24 hours.) 
Sacrum This image shows a number of different tissue types (soft tissue, muscle and bone) in a single image by selection of different thresholds and different cuts through the data.
