This was the approach taken by Charles Mistretta and his research team, who in 2003 pioneered a 3-D imaging technology that captures multiple, real-time images of an afflicted area of the body and displays them dynamically. The new technology allows doctors to view vascular obstructions in even the tiniest of blood vessels. To commercialize this breakthrough, Mistretta licensed the technology to GE Healthcare, which incorporated it into its MRI machines.
