Abstract
Certain embodiments of the present invention provide a method and system for real-time motion correction in compound ultrasound imaging. Certain embodiments include receiving an image frame, estimating motion between the image frame and a previous image frame, updating a previous motion estimate with the estimated motion to form an updated motion estimate, and correcting the image frame and the previous image frame using the updated motion estimate. The method may also include forming a compound image from the image frames. In an embodiment, motion may be estimated between the image frame and a previous frame using cross correlation, reference point registration, and/or other estimation method, for example. The image frame and the previous image frame may be corrected using the updated motion estimate in an affine transformation or other correction method, for example. In an embodiment, the method provides real-time correction as image frames are being received.
