  • Patent number: 8246545
    Abstract: A phased array ultrasound transducer is made from a plurality of independently excitable elements that are arranged in a row in the azimuthal direction, configured so that azimuthal aiming of an outgoing ultrasound beam is controlled by timing the excitation of the elements. The geometry of the elements is configured to focus the outgoing beam in the elevation direction so as to improve the images of target regions located at or about a particular radial distance. In some embodiments, this is accomplished by forming each element from a plurality of subelements that are stacked in the elevation direction, with the subelements of any given element all (a) wired together and (b) positioned at about the same distance from a substantially rod-shaped focal region.

  • Patent number: 8241301
    Abstract: A guide puncturing needle which is integratively used with a scanning and detecting device, such as CT, MRI or the like, and provides puncturing, biopsy, injection, implanting, and the physical diagnose and therapy, such as RF, microwave, freezing, laser and the like, and a puncturing guide method for applying the puncturing needle to puncture are provided. Since the guide puncturing needle is provided with a needle-entering angle guide means (2), a puncturing layer levelling component (31), a needle-entering reference line levelling component (32), whether the CT gantry and the MRI scanning layer are at any angle, the actual needle-entering layer is always adjusted to just superpose to the CT scanning layer, the actual needle-entering angle is always just the same as the needle-entering angle needed for the scanning and detecting device, thus allow the puncturing needle to arrive at the focus point exactly accurately.

  • Patent number: 8235903
    Abstract: An implantable, remotely controlled medical device that incorporates an imaging/therapy ultrasound system may be minimally invasive and equipped with an anchoring portion for securing the device within a human body.

  • Patent number: 8226560
    Abstract: An ultrasonic image 105, 106 is captured by an ultrasonic probe 104. A reference image 111 is obtained by extracting a tomographic image corresponding to the scan plane of the ultrasonic image from volume image data that is pre-obtained by a diagnostic imaging apparatus 102 and that is stored in a volume-data storing unit 107. The ultrasonic image and the reference image 111 are displayed on the same screen 114. In this case, of the reference image, a portion corresponding to the view area of the ultrasonic image is extracted and the resulting reference image having the same region as the ultrasonic image is displayed as a fan-shaped image.

  • Patent number: 8202220
    Abstract: An ultrasound diagnostic apparatus which forms a three-dimensional bloodstream image by reference to volume data obtained from a three-dimensional space within a living organism. Binarization processing and three-dimensional labeling processing are applied to velocity volume data, to thereby generate three-dimensional mask data. At this time, because a bloodstream object has a larger volume size than a noise object, this difference in volume size is utilized to discriminate between a bloodstream portion and a noise portion. Bloodstream volume data are then generated from the velocity volume data and by reference to the three-dimensional mask data. Then, a three-dimensional bloodstream image is formed by reference to the bloodstream volume data.

  • Patent number: 8187187
    Abstract: Shear wave imaging is provided in medical diagnostic ultrasound. A region is imaged to determine a location in which to calculate shear velocity. The shear velocity is estimated for the location. The imaging may guide the identification of the location, reducing the time to determine useful shear information. The estimate of shear may be validated, such as using cross-validation, to indicate the confidence level of the shear value. The shear velocity may be displayed relative to a scale of shear velocities associated with a type of tissue, such as tissue for an organ. The location on a scale may be more intuitive for a user.

  • Patent number: 8180427
    Abstract: The present invention provides an apparatus and method for non-invasively sensing pulse rate and blood flow anomalies using a localized, uni-directional, and constant magnetic field. The apparatus comprises a magnetic source for producing the magnetic field, a signal acquisition module with a magnetic sensor for detecting the modulations of the magnetic field caused by the blood flow; and a signal processing module for processing the acquired signals so as to produce data of pulse rate and blood flow anomalies. The method senses pulse rate and blood flow anomalies by providing a localized, uni-directional, and constant magnetic field in proximity to a blood vessel; detecting the variations of the magnetic field caused by the flow of pulsatile blood within the blood vessel; and processing the signals of the detected variations so as to monitor the blood flow.

  • Patent number: 8180430
    Abstract: A method for position tracking includes using first and second field generators located at respective different first and second locations to generate respective first and second magnetic fields in a vicinity of first and second objects. The first and second fields are measured using first and second position sensors respectively associated with the first and second objects. First and second potential relative coordinates of the first object relative to the second object are calculated responsively to the first and second magnetic field. The potential relative coordinates are processed in order to determine a correct relative coordinate of the first object relative to the second object.
