Abstract

Provided are methods and systems for movement correction in an MRI environment. In one aspect, provided are systems and methods for movement correction, comprising receiving a first plurality of images from a first scan of a subject with a first camera, receiving magnetic resonance imaging (MRI) images obtained concurrently with the first scan, correlating the first plurality of images obtained from the first scan with the MRI images, resulting in motion correction data, and providing the motion correction data to an MRI system, wherein the MRI system adjusts scanning according to the motion correction data.
