摘要： Multifunctional ultrasound systems and methods for body section registration and mapping of microbubble dynamics. A system is provided that includes one or more micromachined ultrasonic transducer arrays (MUTAs) configured to capture a high-resolution image of at least a portion of a body section using ultrasound and monitor microbubble activity during ultrasound treatment. The system includes an image registration module configured to spatially register the high-resolution image with a reference image. The system includes electronics configured to control one or more of drive signal amplitude, frequency filtering, multiplexing, and DC bias voltage. The system can be configured to control ultrasound treatment based on the monitoring of the microbubble activity during treatment.

摘要： An ultrasound transducer has a control circuit with an array of circuit portions which together define a circuit area. cMUT elements are provided over the top of the control circuit. Vias provide a coupling between each cMUT element and a respective one of the circuit portions beneath. The vias are located at spaces between the cMUT elements and connect to the circuit portion beneath at a position relative to the shape of the circuit portion. The pitch of the array is greater than the pitch of the circuit portions in at least one direction of the array such that in said at least one direction, the cMUT elements extend beyond one or both sides of the circuit rea. This makes tiling easier and enables a modular design.

摘要： Disclosed are a flexible vibration cushion and a method of controlling the same. The flexible vibration cushion may include a cover member, a first soft filler material filled in the cover member; and a vibration generation device including components made of a soft material and disposed in the soft filler. The vibration generation device is configured to generate vibration as an electrostatic force is repeatedly generated and released. The vibration generation device may be applied in a vehicle part, e.g., headrest, thereby minimizing the foreign body sensation acting on the user’s skin while delivering soft and various senses of vibrations to the user.

摘要： An ultrasound transducer unit including a plurality of ultrasound transducers transmits and receives ultrasound waves to and from an inside of a subject. In a case where a checking operation unit is operated, a controller controls a driving voltage supply unit such that a driving voltage is supplied with all of the plurality of ultrasound transducers as driving target transducers. In a case where the checking operation unit is operated, a depolarization determination unit calculates, for each ultrasound transducer, a reception sensitivity in a case where an ultrasound wave is received by driving all of the plurality of ultrasound transducers as the driving target transducers, and determines whether or not a depolarization determination value calculated from the reception sensitivity of each ultrasound transducer satisfies numerical conditions. If the numerical conditions are satisfied, a polarization voltage supply unit supplies a polarization voltage to each of the plurality of ultrasound transducers.
