In order to obtain a predetermined ultrasonic wave field in a homogeneous internal part of a medium masked by an aberrating barrier, an ultrasonic lens is interposed between the emitting ultrasonic probe and the aberrating barrier. The ultrasonic lens is calculated by using a model of the medium comprising a mapping of ultrasonic wave propagation properties obtained from actual imaging of the medium such that when the ultrasound probe sends a predetermined ultrasonic wave, said predetermined wave generates the predetermined objective ultrasonic wave field in the medium.

An ultrasonic cleaner is provided. The ultrasonic cleaner includes: a first ultrasonic vibrator configured to generate a first ultrasonic wave; a first oscillator configured to drive the first ultrasonic vibrator; a wash tank configured to store a detergent solution; and an attenuation mechanism configured to damp vibration of the wash tank. The wash tank includes a parabolic surface which is a recessed surface facing a vibration surface of the first ultrasonic vibrator, and is configured to reflect the first ultrasonic wave to a focal position where an object to be cleaned is placed. The vibration of the wash tank is generated by the first ultrasonic wave impinging on the wash tank.

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.

Method and device to create energized polymers that can be used for pain relief, comprised of an ultrasound system that ultrasonically energize polymers that can then be used to provide an analgesic effect. Ultrasound waves are delivered to a polymer through direct contact, through a coupling medium, or without contact in order to energize the polymer. Other energies such as such as UV, microwave, laser, electricity, RF, sun, light, magnetic/electromagnetic, et can also be used to energize the polymer. The energized polymer can be immediately placed on a user to provide an analgesic effect, or the energized polymer can be placed storage material and removed at a later time to be placed on a user to provide an analgesic effect.
