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. 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.

Abstract: Sparse arrays of transducer elements may be beneficial in providing ultrasound transducer probes with a wide total aperture while containing a manageable number of transducer elements. Sparse arrays made with bulk piezoelectric materials or with arrays of micro-elements can be effectively with ping-based multiple aperture ultrasound imaging techniques to perform real-time volumetric imaging.

Abstract: Systems and methods are disclosed for performing ultrasound imaging using biphasic driving and/or reception for ferroelectric ultrasound elements having propagation and lateral electrode pairs. Electrode pairs are driven using biphasic drive signals, where the drive signals applied to the respective pairs of electrodes are provided with a phase difference therebetween, and where a time delay may be added between the drive signals to further increase the power of the emitted ultrasound. In some example embodiments, passive determination of the direction and/or location of an acoustic source relative to a multiaxial ultrasound transducer is determined based on the voltages detected at the propagation electrodes and the lateral electrodes the multiaxial transducer, according to a pre-determined relationship between the electrode voltages and one or more directional angles. A plurality of multiaxial ultrasound transducers may be employed to improve the accuracy of the estimated direction and/or location of the acoustic source.

Abstract: While 3D ultrasound imaging is becoming a powerful tool in medical field. the main drawback is the difficulty to image large 3D volume. mainly related to the dimensions of the 2D array of transducers. In order to not lose in spatial resolution, it is necessary to use an array of transducers. wherein the size of the transducers does not exceed the wavelength of the ultrasound wave. Such requirement leads to dimensions of array for imaging large 3D volume which are not reachable or at too high cost with the current technology. The present disclosure overcomes the above technology limitation by using greater transducers, and where each transducer has a reception surface with a curved shape or is fitted with an acoustic lens. Such configuration of transducers leads to 2D array of transducers suitable for imaging large 3D volume, as a brain or a heart. with high resolution and high sensitivity.
