Abstract: 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. In some aspects, an acoustic couplant device includes an acoustic coupling component including a sonolucent coupling medium (SCM) material; and a coupling assembly to attach the acoustic coupling component to a housing of an array of transducer elements, the coupling assembly comprising: a bracket having a first portion at least partially embedded within the SCM material of the acoustic coupling component and a second portion at least partially extending out of the acoustic coupling component, and a fastener coupled to at least the second portion of the bracket and configured to attach the second portion of the bracket to the housing.

Abstract: Techniques, systems, and devices are disclosed for synthetic aperture ultrasound imaging using spread-spectrum, wide instantaneous band, coherent, coded waveforms.

Abstract: 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.

Abstract: Disclosed are compositions and articles for a semi-rigid hydrogel material that provides an acoustic coupling medium for ultrasound diagnostic and treatment techniques. In one aspect, a hydrogel material for an acoustic coupling medium includes a sodium alginate block copolymer, a dimethylacrylamide monomer, and water. In some implementations, the sodium alginate block copolymer is present in an amount of about 0.5 wt % to about 25 wt %, the dimethylacrylamide monomer is present in an amount of about 1 wt % to about 40 wt %, and the water is present in an amount of at least about 50 wt % of the total weight of the hydrogel composition.

Abstract: Disclosed are articles, devices and systems providing a semi-rigid acoustic coupling medium for ultrasound diagnostic and treatment techniques. In some aspects, an acoustic coupling article includes a semi-rigid acoustic coupling medium (SACM) able to conform to a receiving body through deformation of the SACM body in order to propagate an acoustic signal within the SACM to and from the receiving body. In some embodiments, the SACM is configured in a shape having one or more attachment portions located at one end of an acoustic interface portion, such that the acoustic interface portion is operable to contact the receiving body to propagate the acoustic signal and the attachment portions are configured to be secured by an acoustic probe device to transmit and receive the propagated acoustic signal.
