Acoustic damping for ultrasound imaging devices
An ultrasound imaging device includes an ultrasound transducer module disposed within a housing and a flowable acoustic damping material disposed on at least one surface located within an interior of the housing. The flowable acoustic damping material may be a Teflon™-containing gel material, in contact with at least one internal surface of the imaging device to provide acoustic damping.
Ultrasonic probe with heat dissipation members arranged in center of backing layer
An ultrasonic probe has a transduction layer in which a plurality of transducers are placed, a backing layer provided at a rear side of the transduction layer with a wiring layer therebetween, and a plurality of heat dissipation members provided in the backing layer. The plurality of heat dissipation members extend in a line form in the backing layer, and are placed with an aligned direction of extension. An area occupancy percentage of the heat dissipation member at a center region of the backing layer is larger than that at an outer side of the center region. The center region is not positioned at ends of the cross section intersecting the direction of extension of the heat dissipation member, includes a center of gravity of the cross section, and occupies an area less than or equal to a half of an area of the cross section.
Ultrasound system, method and computer program product
An ultrasound system is disclosed comprising an ultrasound transducer array (100) comprising a plurality of ultrasound transducer cells (130), each of said cell having an independently adjustable position and/or orientation such as to conform an ultrasound transmitting surface of the cell to a region of a body and a controller (140). The controller is configured to register the respective ultrasound transducer cells by simultaneously operating at least two ultrasound transducer cells in a transmit mode in which the cells transmit distinguishable ultrasound signals and operating the remaining ultrasound transducer cells in a receive mode. The controller extracts time-of-flight information of the respective ultrasound signals between transmitter and receiver and by systematically selecting different ultrasound transducer cells as transmitters, the controller collects sufficient time-of-flight information from which the respective position and/or relative orientation of the ultrasound transducer cells within the ultrasound transducer array may be derived. A method for operating the ultrasound system in this manner as well as a computer program product is also disclosed.
Ultrasonic Endocavitary Imaging System and Method
An ultrasonic endocavitary imaging system for developing an image of a portion of a body cavity includes an elongate probe having a longitudinal axis, a distal end configured for insertion into the body cavity, a proximal end opposite to the distal end. The system also includes a shaft rotatably mounted in the probe, in a manner supporting rotation about the longitudinal axis, and having a proximal end protruding from the proximal end of the probe and a distal end opposite to the proximal end. The system further includes handle pivotally attached to the proximal end of the shaft and configured to rotate the shaft within the probe and an image capture assembly. The image capture assembly includes a piezo crystal array, the array coupled to the distal end of the shaft and having an axis aligned with the longitudinal axis, the array configured to cause capture of an ultrasound image of the interior of the body cavity lying in a plane through which the longitudinal axis passes, so that, when the shaft is rotated within the probe by means of the handle, the plane is correspondingly rotated about the longitudinal axis, causing generation of swept image data in the interior of the body cavity. The image capture assembly further includes a radio frequency transceiver disposed in the probe and coupled to the piezo crystal array, the transceiver configured for transmitting the image data from the piezo crystal array to a computing device of a user.
