INTEGRATION OF T2-PREPARATION AND MOTION TRACKING IN MAGNETIC RESONANCE IMAGING

摘要

An embodiment in accordance with the present invention provides concurrent measurement of motion during T2-weighted magnetic resonance imaging. The present invention combines T2 preparation, a module used to impart T2 contrast, and motion measurement, tracking, and/or correction. The present invention provides for the expedition of more efficient motion compensation during T2-weighted imaging. The proposed invention can be used to provide a variety of measurements of motion, with no overhead in imaging time. The proposed invention also enables T2 contrast imaging to be executed while a subject is breathing freely, without the additional time cost associated with the standard motion tracking methodologies.

1. A method of obtaining a corrected image of a subject comprising:
using a T2 preparation module comprising RF pulses and gradients to obtain a base magnetic resonance (MR) image of the subject; inserting motion tracking elements into the T2 preparation module; determining motion information from the motion tracking elements; and correcting the base MR image of the subject using the motion information.
