1. A method of processing ultrasound images of media in which an ultrasound transducer is used to acquire imaging data, the method comprising: acquiring ultrasound imaging data of the media from the ultrasound transducer; determining relative motion between the media and the ultrasound transducer; and processing the acquired data to generate images of the media for display in which more acquired data is utilized in image regions having lower levels of relative motion between the media and the transducer than in regions that have higher levels of relative motion for generating an image.
