Abstract
A method and an apparatus are provided for dynamic, real-time adaptive focusing for ultrasound imaging. Aberration delay correction values, corresponding to an aberration region in an imaged subject, are measured concurrently during B-mode imaging scan lines and updated at the scan line rate. The measured aberration delay correction values are then applied concurrently to correct the focus of all transmitted and received ultrasound scan lines, regardless of the imaging mode, scan geometry, or imaging frequencies.
