An ultrasonic piezoelectric transducer device includes a transducer array consisting of an array of vibrating elements, and a base to which the array of vibrating elements in the transducer array are attached. The base include integrated electrical interconnects for carrying driving signals and sensed signals between the vibrating elements and an external control circuit. The base can be an ASIC wafer that includes integrated circuitry for controlling the driving and processing the sensed signals. The interconnects and control circuits in the base fit substantially within an area below the array of multiple vibrating elements.

Ultrasound transducer element arrays using acoustic ensonification drive patterns via a patient interface for sonosensitizer activation in sonodynamic therapy. Incoherent acoustic field generation varying phase, frequencies, and/or amplitude via controlled delivery of low intensity planar acoustic waves. Method includes generating a first and a second signal to generate respective acoustic ensonification drive patterns with phase, frequency, and amplitude and generating at least one relative phase, frequency or amplitude difference to generate a third incoherent acoustic ensonification pattern to activate a sonosensitizer. Calibration and complementary therapy procedures to improve cell susceptibility of cells to sonodynamic therapy are disclosed.

A multi-focal shockwave output handle unit for an extracorporeal shockwave therapy device using a multi-piezoelectric configuration includes a high-intensity focused ultrasound generator that is provided on a front end part of a handle that is provided to be gripped by a user, and generates high-intensity focused ultrasound (HIFU) on the basis of an applied electric signal; a cover unit that is connected to the front end part of the handle; a radiation-surface base unit that is connected to a front end part of the cover unit; a piezoelectric ceramic unit that includes a plurality of piezoelectric ceramic members arranged on the front inner curved surface of the cover unit or the rear outer curved surface of the radiation-surface base unit; and a gel pad unit that is connected to a front end part of the radiation-surface base unit.

An acoustic wave probe includes a support member including a plurality of through holes and a concave portion which is concave facing an object disposed in a measurement position at the time of measurement, and an acoustic wave transducer unit including at least a transducer. The acoustic wave transducer unit is mounted in the through hole facing approximately a center of curvature of the concave portion, and a thickness of the acoustic wave transducer unit is thinner on a side of the center of curvature.

A multi-array ultrasound system for haptic engagement is provided. The system may include a computing device with a processing system, a tracking device communicatively coupled to the processing system, two or more ultrasound transducer arrays including a plurality of ultrasound transducers, and a driver communicatively coupled to the processing system and the two or more ultrasound transducer arrays.

Ultrasound transducer arrays are provided to for example, initiate and enhance therapeutic treatments with a normalized, randomized, and/or incoherent acoustic pressure field. Optimizing pressure uniformity (peak and average pressures) throughout the incoherent pressure field, and maximizing volume of that incoherent field may be achieved through controller filtering steps to assign unique element waveform phases for each element in the array. Ultrasound may be used alone, to activate a drug, pro drug, sonosensitizer, and/or microbubble additives, and can be combined with other energy (e.g., radiation, magnetism), for treatments including cancer, neurological disease, mood condition, sleep apnea, inflammation, and/or orthopedic diseases, and opening the blood brain barrier to improve access to the drugs and additives. Ultrasound transducer systems may used with a cooling system, an alignment device a monitoring system an authorization system (e.g., identification bar code, key) and/or a treatment planning system.

A laundry appliance includes a drum that rotationally operates within a tub. A fluid delivery system selectively delivers wash fluid to the drum. A rotator rotationally operates within the drum. The rotator selectively operates independent of the drum and about a common rotational axis of the drum and the rotator. A sanitizing mechanism includes an ultrasonic transducer. The ultrasonic transducer selectively delivers waves of an ultrasonic frequency into an amount of the wash fluid disposed within the drum and the rotator. The ultrasonic frequency generates air bubbles and causes cavitation of the air bubbles that directs a micro jet of air through the wash fluid and into articles being processed within the drum.
