The invention relates to a molded gel body (1), the production thereof and the use thereof in ultrasonography in the medical or dental field. In particular, the molded gel body (1) is used to detect and localize dental cavities in the jawbone by means of through-transmission alveolar ultrasonography (TAU). The molded gel body (1) has a receptacle (2) for receiving an ultrasound transmitter and/or receiver (7). The molded gel body (1) and the receptacle (2) are preferably adapted to the shape of the ultrasound transmitter and/or receiver. For easier handling, the molded gel body (1) is inserted into a flexible, biocompatible protective cover (6) which, like the receptacle (2), can be filled with a non-dimensionally stable ultrasound gel. To produce the molded gel body (1), cuboids of a dimensionally stable gel of the appropriate size are preferably cut open over the narrow lateral surfaces of the cuboid, but preferably not completely cut through and only over three of the four sides to produce the receptacle (2) or, if not completely cut open, closed or glued on the edges only over two of the four sides.

A cranial plug includes a cranial plug housing having a window recess with an access hole. A window is shaped and dimensioned for positioning with the window recess of the cranial plug housing.

An ultrasound imaging system includes a thermally conductive frame and a number of electronic components and a display that are sealed within the frame. The frame further includes a plenum extending through the frame with surfaces that are thermally coupled to the electronic components and the display. An active cooling mechanism, such as one or more fans, moves air through the plenum to remove heat generated by the electronic components and display. The plenum is environmentally sealed so that moisture, dust, air or other contaminants drawn into the plenum do not contact the sealed electronic components and display in the frame.

Embodiments provide an ultrasound treatment system. In some embodiments, the system includes a removable transducer module having an ultrasound transducer. In some embodiments, the system can include a hand wand and a control module that is coupled to the hand wand and has a graphical user interface for controlling the removable transducer module, and an interface coupling the hand wand to the control module. The interface may provide power to the hand wand or may transfer a signal from the hand wand to the control module. In some embodiments, the treatment system may be used in cosmetic procedures on at least a portion of a face, head, neck, and/or other part of a patient.

A smart screw according to an embodiment may comprise: a screw main body which penetrates an artificial joint including a shell disposed on a hip joint of an object and a liner disposed on the inner surface of the shell and is then inserted into the hip joint; a transducer including a coupling layer that senses a sound wave signal reflected from the liner, a piezo-electric layer formed to determine a frequency of the sound wave signal, and a sound absorbing layer for absorbing the sound wave signal; and a processing module for generating a sound wave signal toward the liner and receiving the sound wave signal sensed by the coupling layer, measuring the thickness of the liner on the basis of the received sound wave signal, and transferring data about the measured thickness of the liner to the outside.

An ultrasound emission device includes a generation part which generates an ultrasonic wave to an object side, and a bag containing a sealed liquid on the object side of the generation part. The generation part includes a piezoelectric element for generating the ultrasonic wave. The piezoelectric element includes a first surface facing the object side and a second surface facing away from the object side. The piezoelectric element includes, between the first and second surfaces, a piezoelectric layer which extends along the first and second surfaces, and a pair of electrodes which are superposed on two surfaces of the piezoelectric layer. The piezoelectric element flexurally deforms so that the first and second surfaces flex to the same side. The first surface is exposed to the inside of the bag to contact the liquid. The second surface is isolated from the liquid and is in contact with a gas.

High frequency ultrasound transducers configured for use with high frequency ultrasound diagnostic imaging systems are disclosed herein. In one embodiment, an ultrasound transducer includes a concave lens having an average thickness in a center portion that that is substantially equal to an odd multiple a ¼-wavelength of the center frequency of the ultrasound transducer.

Microresonator structures including a top polymer film layer, a bottom polymer film layer, and a smart hydrogel structure sandwiched between the polymer film layers. An ultrasound resonator cavity having a resonance frequency is defined between the top and bottom polymer layers, and the smart hydrogel structure is configured to provide a change in height to the ultrasound resonator cavity due to volumetric expansion or contraction of the smart hydrogel structure, in response to interaction of the smart hydrogel structure with one or more predefined analytes in an in vivo or other environment. Related methods of use for determining the presence or concentration of a given target analyte, as well as methods of fabricating such microresonator structures are also described.

An ultrasound probe according to an embodiment includes a base material, a first organic layer, and a second organic layer. The base material contain polyolefin. The first organic layer is formed on the outer surface of the base material and contains epoxy resin and silicate oligomer. The second organic layer is formed on the outer surface of the first organic layer and has hydrophilicity.

Arrangements described herein relate to a headset system and a method to manufacturing the headset system, the headset system including a headset configured to lay on top of a surface and to support a head of a subject when the subject is in a supine position or a reclined position, at least one probe adjustment mechanism, and a probe coupled to the at least one probe adjustment mechanism and configured to emit acoustic energy.
