摘要： Techniques, systems, and devices are disclosed for synthetic aperture ultrasound imaging using a beamformer that incorporates a model of the object. In some aspects, a system includes an array of transducers to transmit and/or receive acoustic signals at an object that forms a synthetic aperture of the system with the object, an object beamformer unit to (i) beamform the object coherently as a function of position, orientation, and/or geometry of the transducers with respect to a model of the object, and (ii) produce a beamformed output signal including spatial information about the object derived from beamforming the acoustic echoes; a data processing unit to process data and produce an image of the object based on a rendition of the position, the orientation, the geometry, and/or the surface properties of the object, relative to the coordinate system of the array, as determined by the data processing unit.

摘要： Disclosed are methods for scalable, cost-effective, and rapid production manufacturing and packaging a semi-rigid acoustic coupling medium that can be used for ultrasound diagnostic and treatment systems and techniques. In some aspects, a method includes forming a staged solution by adding together a stock solution comprising a monomer and a block copolymer in deoxygenated water and a primed solution comprising a covalent crosslinking agent and a catalyst; forming a gel-sol by mixing the staged solution with a first network activator solution comprising a monomer activator and a second network activator solution comprising a block copolymer activator; dispensing the gel-sol into a mold; and curing the gel-sol in the mold to produce a semi-rigid acoustic coupling material, where the method is carried under an inert atmosphere.

摘要： Devices, systems, and methods are disclosed for use in tomographic ultrasound imaging, large aperture ultrasound imaging and therapeutic ultrasound that provide for coupling acoustic signal transducers to body structures for transmitting and receiving acoustic signals. The acoustic signal transmission couplants can conform to the receiving medium (e.g., skin) of the subject such that there is an acoustic impedance matching between the receiving medium and the transducer. In one aspect, an acoustic coupling medium includes a hydrogel including polymerizable material that form a network structured to entrap an aqueous fluid inside the hydrogel. The hydrogel is structured to conform to the receiving body, and the acoustic coupling medium is operable to conduct acoustic signals between acoustic signal transducer elements and a receiving medium when the hydrogel is in contact with the receiving body such that there is an acoustic impedance matching between the receiving medium and the acoustic signal transducer elements.
