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).
