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: An ultrasound transducer array is incorporated in a light-weight, conformable, and wearable patch that may be used to deliver, monitor, and control localized transcranial focused ultrasound (tFUS). The patch may include full-duplex transmit-receive circuitry that may be used for continuous monitoring of transcranial focused ultrasound (tFUS) application. The circuitry may include a circulator. The ultrasound transducer array may be coupled to an aperture interface having irregularly sized or shaped channel conductors to provide a coarse aperture for the array. The coarse aperture may be designed using a method that provides a reduced channel count.

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). Ultrasound systems 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: Embodiments are directed to a method for use in ultrasound imaging of matter in a region comprising providing wave energy into the region and transducing wave energy returned from the region to form a set of receive signals defining received signal data. The method comprises separating linear and nonlinear components of the received signal data based on a second order Volterra model. The method also comprises computing an estimate of a tissue acoustic nonlinearity parameter, B/A, using a ratio of the nonlinear component to the linear component, and identifying tissue characteristics of the matter in the region using the B/A.

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 multi-channel 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, multi-modal 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.
