  • Patent number: 9339258
    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.

  • Patent number: 9295444
    Abstract: The disclosed embodiments include a method, system, and device for conducting ultrasound interrogation of a medium. The novel method includes transmitting a non-beamformed or beamformed ultrasound wave into the medium, receiving more than one echoed ultrasound wave from the medium, and converting the received echoed ultrasound wave into digital data. The novel method may further transmit the digital data. In some embodiments, the transmitting may be wireless. The novel device may include transducer elements, an analog-to-digital converter in communication with the transducer elements, and a transmitter in communication with the analog-to-digital converter. The transducers may operate to convert a first electrical energy into an ultrasound wave. The first electrical energy may or may not be beamformed. The transducers also may convert an echoed ultrasound wave into a second electrical energy.

  • Patent number: 9265473
    Abstract: An embodiment in accordance with the present invention provides a method for non-invasively determining the functional severity of arterial stenosis in a selected portion of an arterial network. The method includes gathering patient-specific data related to concentration of a contrast agent within an arterial network using a coronary computed tomography angiography scan (CCTA). The data can be gathered under rest or stress conditions. Estimation of a loss coefficient (K) can be used to eliminate the need for data gathered under stress. The data is used to calculate a transluminal attenuation gradient (TAG). The data may be corrected for imaging artifacts at any stage of the analysis. TAFE is used to determine an estimate of flow velocity. Once velocity is determined, pressure gradient, coronary flow reserve, and/or fractional flow reserve can be determined through a variety of methods. These estimates can be used to estimate functional severity of stenosis.

  • Patent number: 9261595
    Abstract: A memory alloy is used during manufacture of a transducer. The memory of the alloy may correct for deviations or bending during manufacture, such as a superelastic alloy returning an array to a flat state after being twisted during handling. The memory of the alloy may cause a desired change in array geometry during manufacture, such as a shape memory alloy twisting an array into a curved or helix due to applied heat. The array may be fixed in place by the memory alloy or bonding after positioning by the memory alloy, preventing further substantial alteration.

  • Patent number: 9226729
    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.

  • Patent number: 9226663
    Abstract: Described herein are systems and methods for optically isolating components of an optical sensor in physiological monitoring devices worn by a user to sense, measure, and/or display physiological information. An optical sensor may be mounted in the rear face of the device, emit light proximate a targeted area of a user's body, and detect light reflected from the targeted area. Optically isolating structure may be located at least partially between one or more components of the optical sensor to ensure that light detected by the sensor is light reflected from the targeted area rather than light emitted directly from a light source and/or ambient light. The optically isolating structure may, in some cases, extend between a contact surface of the monitoring device to a base portion of the sensor components or a surface of a circuit board to which the sensor components are mounted.

  • Patent number: 9216065
    Abstract: Apparatus and methods are described including acquiring a plurality of image frames of a portion of a subject's body. At least one of the image frames is designated as a baseline image frame, a shape of the portion in the first baseline image frame being designated as a baseline shape. A non-baseline-shape image frame is deformed, such that the shape of the portion becomes more similar to the baseline shape of the portion than when the portion in the non-baseline-shape image frame is not deformed. A composite image is formed that is of higher clarity with respect to anatomy of the portion, relative to each of the acquired image frames, by averaging at least the deformed non-baseline-shape image frame with the baseline image frame. The composite image is displayed on a display. Other applications are also described.
