New MRI algorithm could reduce the time patients spend in the machine from 45 to 15 minutes

New algorithm could substantially speed up MRI scans. 

Faster scans could reduce the time patients spend in the machine from 45 to 15 minutes. Using GPUs (graphical processing units) could improve the speed even more.
