Abstract
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.
Claims15
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.
