Abstract: Methods and devices for treating skin include a skin-contacting portion, an actuator and a processor, wherein activation of the actuator causes surface acoustic waves of Rayleigh, “pseudo” Rayleigh types to be produced on the skin around the actuator. In a location which is under the actuator, the actuator produces tension and repulsion of skin particles. These surface acoustic waves can be used to provide treatment to the skin, including wound healing, non-adhesion of bandages, reduced infection, reduced pain and cosmetic enhancements. The skin-contacting portion may be a patch or bandage, a glove, a hand-held device, or any other suitable configuration. The actuator is incorporated into the skin-contacting portion.

Abstract: Systems and methods are provided herein that generally involve measuring a prostate or other object. In some embodiments, a membrane can be sealed over a digit extension to form a closed volume. The closed volume can be inflated via an inflation tube, and a reference pattern can be disposed within the closed volume along with a measurement assembly. In use, a user can put on the glove, position the membrane in proximity to a rectal wall overlying a prostate, and inflate the membrane. As the user slides their finger across the rectal wall, optical fibers in the measurement assembly can move relative to a reference pattern, and a controller can sense light reflected through the fibers from the reference pattern. The controller can calculate or estimate various attributes of the prostate based on the reflected light, such as the palpable surface width or volume.

Abstract: There is provided an ultrasonic diagnosis apparatus capable of reducing an unnecessary signal component in a reception signal. A plurality of sign bits arranged in the channel direction are extracted from a plurality of element reception signals. A binarization circuit applies binarization processing to the plurality of sign bits to thereby generate a sign data array. An evaluation value computing unit computes an evaluation value (GSCF) based on a DC vicinity component contained in the sign data array on the frequency axis. This evaluation value is used to adjust the gain of the reception signal in a multiplier. With application of the binarization processing, excessive reduction of the reception signal can be prevented. Further, as the DC vicinity component is referenced, the side-lobe component can be appropriately reduced even if a certain degree of fluctuation exists in the main-lobe component.

Abstract: A cryocatheter for introduction into a body vessel or into an organ, with a catheter inner surrounded by a catheter sheath, and with a catheter tip arranged at its distal end, with a feed line for an expansion or cooling agent arranged in the catheter sheath or the catheter inner, and with a balloon, arranged close to the catheter tip, which can be expanded and contracted again by means of the expansion and cooling agent, is to be constructed in such a way that by simple manipulation it can be positioned at a precise target position in the body vessel and, in addition, it minimizes the burden on the patient from invasive interventions. For this purpose, in accordance with the invention an image capture device, with at least one imaging sensor for mapping the region of the vessel around the balloon, is positioned in the region of the catheter tip.
Abstract: The ultrasound diagnostic apparatus, ultrasound image generation apparatus and method transmit ultrasound waves to a subject into which a puncture tool is inserted, receive reflected waves reflected from the subject and the puncture tool, and generate echo signals of time-sequential frames based on the received reflected waves, and generate an ultrasound image of the subject based on the generated echo signals. These apparatus and method generate a differential echo signal between time-sequential frames from the echo signals, perform a tip detection process based on the differential echo signal to thereby detect at least one tip candidate including a tip end of the puncture tool, highlight a tip candidate of the puncture tool detected to thereby generate a tip image, and display the tip image of the highlighted puncture tool so as to be superimposed on the generated ultrasound image.

The ultrasonic probe includes: plural ultrasonic transducers for transmitting ultrasonic waves according to drive signals and receiving ultrasonic echoes to output reception signals; signal processing units for performing orthogonal detection processing or orthogonal sampling processing on the reception signals to generate two signals representing a complex baseband signal; sampling units for sampling the two signals to generate parallel sample data; a serializing unit for converting the parallel sample data into serial sample data; and a transmitting unit for transmitting the serial sample data.
Abstract: There is provided an ultrasonic diagnosis apparatus capable of reducing an unnecessary signal component in a reception signal. A sign data array formed of a plurality of sign data items arranged in an element arranging direction is extracted from a plurality of element reception signals having been subjected to delay processing but having not been subjected to summing processing. A factor computing unit computes a first factor indicating a level of sign coherence in the sign data array and a second factor indicating a sign transit density in the sign data array. The factor computing unit then computes a factor (evaluation value) for adjusting gain of the reception signal, based on the first factor and the second factor.

Abstract: An ultrasonic imaging system produces a sequence of images of the heart during a cardiac cycle. The images are analyzed to determine the motion, displacement, or change in size of segments of the myocardium. In a preferred embodiment the values determined are radial, longitudinal, or circumferential myocardial strain values. The displacement of the myocardial segments may be tracked during the cardiac cycle by speckle tracking or border detection. The motion, displacement, or change in size values for the segments are analyzed to produce a recruitment curve and anatomical display showing the relative times of recruitment of the different segments in the contractile and relaxation motion of the heart. Participation in and achievement of full recruitment may be determined by comparison against an initial recruitment threshold criterion and against a predetermine maximal recruitment milestone level.

Abstract: In order to simplify a manufacturing process and reduce cost and power consumption by providing an ultrasonic diagnostic apparatus including a carrier signal generating circuit excellent in IC implementation, a carrier signal generating circuit for generating an output voltage Vo applied to an ultrasonic probe 41 includes cascaded source follower type NMOSFETs 11 to 14, a variable current source 31, and a constant current source for biasing 32. The probe 41 can be made to generate the output voltage Vo with arbitrary amplitude by controlling a gate voltage V4 by controlling the output current value of the variable current source 31. In addition, a voltage applied to each NMOSFET can be divided by connecting the NMOSFETs 11 to 14 in a multi-stage manner. Accordingly, the withstand voltage of the NMOSFET may be low.
