Medicine: TMSIDK Episode 22
MRI (Magnetic Resonance Imaging) is the gold standard for soft tissue imaging in the body, but the current hardware has a few drawbacks: scanners are gigantic, expensive, loud and require high power. All these factors make it so an MRI scanner can’t travel to a battlefield or to a patient in a remote location.
But a team at the MGH Martino center is developing a portable low-cost MRI scanner for human brain imaging. The prototype scanner can be wheeled into a patient’s room, plugged into a standard outlet and safely operated by a clinician at the patient’s bedside. How? First, instead of imaging the whole body, it only scans the patient’s head. Second, the researchers replaced the standard magnets with a compact permanent magnet that fits around the head mechanically rotates. Then they use complex algorithms to reconstruct the images.
