  • Patent number: 10512444
    Abstract: An ultrasonic diagnostic imaging system is described which assesses regurgitant flow through a mitral valve by color-flow imaging. A Doppler processor produces Doppler velocity measurements of blood flow around a regurgitant valve to identify an iso-velocity surface to be used in the PISA method of regurgitant flow quantification. The velocity measurements are used to color pixels in the colorflow image and are mapped to a plurality of colors for a color bar used with the image. The color bar exhibits distinct color transitions at one or more velocities in the velocity range of the color bar which distinctively identify an iso-velocity surface in the colorflow image. The color bar may be formed with an aliasing velocity in the middle of the bar, between a zero velocity reference color of the bar and an end of the bar, and the aliasing velocity aligned with a desired iso-velocity and used to create the color transition.

  • Patent number: 9390261
    Abstract: The majority of such software attacks exploit software vulnerabilities or flaws to write data to unintended locations. For example, control-data attacks exploit buffer overflows or other vulnerabilities to overwrite a return address in the stack, a function pointer, or some other piece of control data. Non-control-data attacks exploit similar vulnerabilities to overwrite security critical data without subverting the intended control flow in the program. We describe a method for securing software against both control-data and non-control-data attacks. A static analysis is carried out to determine data flow information for a software program. Data-flow tracking instructions are formed in order to track data flow during execution or emulation of that software. Also, checking instructions are formed to check the tracked data flow against the static analysis results and thereby identify potential attacks or errors. Optional optimisations are described to reduce the resulting additional overheads.

  • Patent number: 9322902
    Abstract: A BC-mode image with an improved frame rate in an ultrasound system is formed. A transmit/receive unit forms first and second receive signals responsive to first and second control signals. An image processing unit is configured to form a B-mode image and a C-mode image based the first and second receive signals and to combine them to form a BC-mode image. The control signal generates a third control signal for a B-mode scan along scan lines, which are not within the color box to form third receive signals. The control unit repeatedly generates the second and third control signals. The image processing unit is further operable to form a B-mode image based on the third receive signals and the second signals.

  • Patent number: 9192359
    Abstract: Vector Doppler Imaging (VDI) improves on conventional Color Doppler Imaging (CDI) by giving speed and direction of blood flow at each pixel of a display generated by a computing system. Multiple angles of Plane wave transmissions (PWT) via an ultrasound transducer conveniently give projected Doppler measurements over a wide field of view, providing enough angular diversity to identify velocity vectors in a short time window while capturing transitory flow dynamics. A fast, aliasing-resistant velocity vector estimator for PWT is presented, and VDI imaging of a carotid artery with a 5 MHz linear array is shown using a novel synthetic particle flow visualization method.

  • Patent number: 9165552
    Abstract: The present invention enables ultrasonic propagation time values after correction of refraction to be calculated in parallel for each receive channel, by using a recurrence relation in the depth direction. Moreover, accumulation of errors can be avoided by using an accurate propagation time value obtained in advance at a reference depth to correct the propagation time value each time the reference depth is reached. For this error correction, the recurrence relation to calculate the propagation time value can be an approximate expression. For example, the propagation time value can be calculated using the inclination of reference propagation time values between reference depths. In an actual circuit, received signals are sequentially stored in a memory, and a receive beam is formed by calculating an address position corresponding to the propagation time value of the ultrasonic wave, and adding the received signals stored in the calculated addresses.

  • Patent number: 9125586
    Abstract: A method displays ultrasound color flow image data in a plurality of output frames by continuously acquiring color flow image data. Each output frame includes a plurality of scan lines that collectively represent a field of view for an ultrasound image. The method includes sequentially transmitting a plurality of ultrasound beams. For each of the transmitted beams, multiple receive beams are formed along respective parallel scan lines. As the sequence progresses, sets of co-linear receive beams are formed along each of the respective scan lines at a predetermined rate both within a particular frame and between successive frames. The method also includes processing the sets of co-linear receive beams along each of the respective scan lines to generate color flow image data corresponding to the respective scan lines, and displaying a color flow image representing the generated color flow image data.

  • Patent number: 9113811
    Abstract: A tissue-image creating unit creates a tissue image including depth values by volume rendering from three-dimensional tissue data stored in a three-dimensional data storage unit. A blood-flow data converting unit scatters a blood flow in three-dimensional blood-flow data stored in the three-dimensional data storage unit into particles, and converts the three-dimensional blood-flow data into three-dimensional particle data. A blood-flow image creating unit creates a blood-flow image including depth values from the three-dimensional particle data. A composite-image creating unit then creates a composite image by coordinating the order of rendering particles and tissue based on the depth values of respective pixels included in the tissue image and the depth values of respective particles included in the blood-flow image. A display control unit then controls display of the composite image so as to be displayed in order onto a monitor included in an output unit.
