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.

摘要： 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.

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： Techniques, systems, and devices are disclosed for spatial and temporal encoding of transmission in full synthetic transmit aperture imaging to achieve optimal spatial and contrast resolution and large signal-to-noise ratio for medical imaging applications with fewer signal transmissions, which can be equal to or less than the number of array elements within the aperture. In some aspects, a method of signal transmission is disclosed that includes a sequence of one or more sets of transmissions on a plurality of elements with unique, random, and/or optimized combinations of waveforms using amplitude and phase, and/or delay encoding. Sets of echoes corresponding to the sequence are beamformed such that fewer transmissions are needed than the number of array elements within the aperture, while maintaining complete spatial sampling of the aperture as if sampled according to a full set of synthetic transmit aperture transmissions on the same aperture.
