Abstract
An SNR-adaptive method for processing a plurality of post-detection medical diagnostic ultrasonic images determines a cross-correlation parameter from corresponding multi-dimensional regions of first and second post-detection ultrasonic images, and then uses the cross-correlation parameter to suppress electronic noise in ultrasonic image processing. In some cases the multi-dimensional region of the first and second images are registered prior to cross-correlation to compensate for relative movement between the transducer and the imaged tissue between the first and second images.
