Motion robust magnetic resonance imaging (MOTOR-MRI)

Applications

• MR imaging of patients with Parkinson’s
• MR imaging of small children
• MR imaging of patients with motor dysfunctions

Technology Overview

Magnetic resonance imaging scans are highly susceptible to subject motion, especially when imaging small children or subjects with motor dysfunctions such as Parkinson’s disease. Researchers at the University of Minnesota have developed a for suppressing motion artifacts in anatomical magnetic resonance acquisitions. The technique, MOTOR-MRI, can recover and salvage images that are otherwise heavily corrupted by motion-induced artifacts and blur, rendering them unusable. Contrary to other techniques, MOTOR-MRI operates on the reconstructed images and not on k-space data. It breaks the standard acquisition protocol into several shorter ones and subsequent efficient aggregation in Fourier space of locally sharp and consistent information among them, producing a sharp and motion-mitigated image. MOTOR-MRI can operate independently, or in conjunction with additional motion correction methods. This decreases the overall scan time, which is associated with decreased insurance costs, and decreased overall subject discomfort.
