The Problem:

Magnetic Resonance Imaging (MRI) scanners use strong magnetic fields, radio waves, and field gradients to generate images of the human anatomy. This process is time consuming as data is acquired sequentially and is not fast enough for imaging moving organs like the heart. The magnetic field of an MRI scanner should be strong and highly uniform over the anatomical region that is to be imaged. This is a demanding specification that results in bulky and expensive magnets that need liquid helium - an expensive, non-renewable resource.

The Solution:

The project aims to develop the first liquid helium-free, commercial high-field full body MRI Scanner that impart 3-4x acceleration in the imaging process as compared to current scanners. The technology enables increased patient throughput by enhancing system utilization, and expands the scope of MRI to real-time imaging of moving organs such as the heart and the abdomen.
