Development of new radio frequency pulses to improve 7T MRI

Project Details

The spatial non-uniformity of the RF field (B1) in 7 Tesla MRI scanners presents a real problem for the widespread adoption of these scanners to clinical applications.

Prof Roger Ordidge has been pioneering the development of a new class of MRI pulse sequence designs called STEP pulses that tolerate non-uniform B1 fields so that common MRI sequences can work properly at 7 Tesla to take full advantage of the improved resolution and sensitivity of these scanners.

This work is the subject of several patents and is an active and ongoing field of research.
