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： A hand-held ultrasound system includes integrated electronics within an ergonomic housing. The electronics includes control circuitry, beamforming and circuitry transducer drive circuitry. The electronics communicate with a host computer using an industry standard high speed serial bus. The ultrasonic imaging system is operable on a standard, commercially available, user computing device without specific hardware modifications, and is adapted to interface with an external application without modification to the ultrasonic imaging system to allow a user to gather ultrasonic data on a standard user computing device such as a PC, and employ the data so gathered via an independent external application without requiring a custom system, expensive hardware modifications, or system rebuilds. An integrated interface program allows such ultrasonic data to be invoked by a variety of such external applications having access to the integrated interface program via a standard, predetermined platform such as visual basic or c++.

Broad beams are transmitted, allowing fewer transmit elements and/or more rapid scanning. A multidimensional receive array generates data in response to sequential transmissions, such as transmissions from different angles. The data is combined to increase resolution. A transducer array with offset transmit elements for forming a transmit line source may be used.

摘要： Methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.

摘要： An ultrasound catheter is disclosed for providing substantially real-time images of small cavities. The ultrasound catheter is characterized by separate and distinct materials for backing the transducers and for carrying the electronics components. The separate materials comprise an electronics carrier meeting the requirements for holding the integrated circuitry of the ultrasound device and a backing material displaying superior characteristics relating to reducing ringing and minimizing the effect of other sources of signal degradation in the transducer assembly. Also, in accordance with the present invention, a technique is described for connecting the conductor lines of the separate transducer assembly and electronics body.
