Abstract: A dual-mode ultrasound system provides real-time imaging and therapy delivery using a transducer array. The system may use various imaging modes to provide image data that may be used to select control points within an imaging field of view. The control points along with the image data may be used to solve an optimization problem to achieve desired focusing gains at one or more of the control points. The optimized solution may be used to produce excitation waveforms to generate new image data. The focusing gains may be evaluated and the optimization problem may be iterated until desired focusing gains are achieved. Virtual arrays may be defined and cascaded to provide flexibility in solving the optimization problem.

Abstract: A dual-mode ultrasound system provides real-time imaging and therapy delivery using the same transducer elements of a transducer array. The system may use a multichannel driver to drive the elements of the array. The system uses a real-time monitoring and feedback image control of the therapy based on imaging data acquired using the dual-mode ultrasound array (DMUA) of transducer elements. Further, for example, multimodal coded excitation may be used in both imaging and therapy modes. Still further, for example, adaptive, real-time refocusing for improved imaging and therapy can be achieved using, for example, array directivity vectors obtained from DMUA pulse-echo data.

Abstract: Ultrasound methods provide for the motion tracking of both vessel wall motion and blood flow (e.g., with use of high frame rate ultrasound pulse echo data and speckle tracking both wall motion and flow can be tracked simultaneously).

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).

Abstract: Sub-performing elements of an ultrasound transducer array are detected. The power, such as current, used by or provided to the transmit driver is measured. By driving each element or group of elements separately, defective elements or groups of elements are detected from the amount of power used.
