Abstract

Ultrasound adaptive imaging methods and / or systems provide for modification of waveform generation to drive a plurality of transducer elements. The modification may be based on at least one of contrast ratio or signal to noise ratio as determined with respect to control points in a region of interest. Further, image reconstruction may be performed upon separating, from pulse echo data received, at least a portion thereof received at each ultrasound transducer element from the region of interest in response to the delivered ultrasound energy corresponding to a single frequency of one or more image frequencies within a transducer apparatus bandwidth. The image reconstructed from the separated pulse-echo data corresponding to the single frequency of the one or more image frequencies may be used alone or combined with like image data (e.g., to provide an image representative of one or more properties in the region of interest).

Description

[0001] Cross References to Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 857,442, filed July 23, 2013, which is incorporated herein by reference. Background technique [0003] The disclosure herein relates generally to ultrasound imaging. More particularly, the disclosure herein pertains to ultrasound imaging methods and systems for use, for example, in diagnostic and / or therapeutic applications, such as imaging of complex media such as blood vessels and / or their adjoining regions, intervertebral disc tissue, brain structures, etc. . [0004] Ultrasound imaging is used not only as a modality for detection of cardiovascular disease but also for assessment of response to new anti-atherosclerotic therapies (see Ainsworth et al., "3D Ultrasound Measurement of Changes in Carotid Plaque Volume – A Method for Rapid Tools for the Evaluation of New Therapies”, Stroke, Vol. 36, No. 9, pp. 1904–1909, September 2005) are gai...
