  • SYNTHETIC-FOCUSING STRATEGIES FOR REAL-TIME ANNULAR-ARRAY IMAGING
    Publication number: 20130093901
    Abstract: A method to increase the image formation speed in a digital ultrasound system including annular array of N elements with a plurality of transmit and receive channels. Selectively dropping one or more transmit or receive channels during image formation reduces the amount of data needed to form an image and thus increases the image formation frame rate. The improved frame rate does result in some reduction in resolution, SNR and potentially DOF, but image quality remains at an acceptable level.

  • ANALYZING EXECUTABLE BINARY CODE WITHOUT DETECTION
    Publication number: 20130347104
    Abstract: Analysis of executable binary code is performed without detection by defensive elements embedded within the executable binary code or within a system in which the executable binary code is executing. An identified suspect executable file is disassembled. Statically and dynamically analysis is performed on binary code of the disassembled executable file. An anti-anti-debugging function is implemented by executing program call functions in a manner which avoids detection of a debugging program by the defensive elements embedded within the executable binary code of the anti-debugging function of the executable binary code, thereby avoiding detection by the source of the suspect executable file.

  • Frequency-controlled scanning of ultrasonic beams
    Patent number: 4350917
    Abstract: An ultrasonic wave transducer is formed from a body of piezoelectric material having nonuniform thickness. Each location on the transducer is resonant at a different frequency according to the thickness at that point. By changing the frequency of the applied excitation signal, the origin and direction of the radiation can be altered.

  • Phased array antenna
    Patent number: 5623270
    Abstract: A phased array antenna system compensates for the effects of antenna flexure, vibration and movement, and thereby negates these effects by introducing an appropriate phase or time delay into the signals being radiated from and received by the discrete antenna elements comprising the phased array antenna. This compensation eliminates the need for massive rigid back structures to maintain antenna rigidity, which thereby simplifies antenna design.

  • Ultrasonic systems and methods for contrast agent concentration measureament
    Publication number: 20010001108
    Abstract: The concentration and/or radii of a contrast agent in a fluid can be estimated by acquiring ultrasound spectral data, performing spectral analysis to generate a linear estimation of the power spectrum, and correlating at least one spectral parameter to a predetermined distribution function for the contrast agent. If the mean radius squared of particles is known, then the concentration of contrast agent particles can be calculated. If the concentration is constant, then relative variations in mean radius squared can be determined.
