  • System and method for measurement of shear wave speed from multi-directional wave fields
    Patent number: 9622711
    Abstract: A system and method for measuring material properties of a medium includes producing a multi-directional wave field in the medium and detecting, with a detection system capable of detecting wave fields propagating in a medium, the multi-directional wave field in at least two spatial dimensions over at least one time instance. The system and method also include determining a lowest wave speed, calculating at least one of wave speed and material properties of the medium, and generating a report indicating the at least one of wave speed and material properties of the medium.

  • SYSTEM AND METHOD FOR SHEAR WAVE GENERATION WITH STEERED ULTRASOUND PUSH BEAMS
    Publication number: 20150265249
    Abstract: A system and method for performing a steered push beam (SPB) technique to create multiple foci generated by the interference of different ultrasound push beams to create shear waves and, based thereon, generate a report indicating mechanical properties about an object.

  • ULTRASOUND VIBROMETRY WITH UNFOCUSED ULTRASOUND
    Publication number: 20140046173
    Abstract: Methods for measuring mechanical properties of an object or subject under examination with an ultrasound system and using unfocused ultrasound energy are provided. Shear waves that propagate in the object or subject are produced by applying unfocused ultrasound energy to the object or subject, and measurement data is acquired by applying focused or unfocused ultrasound energy to at least one location in the object or subject at which shear waves are present Mechanical properties are then calculated from the acquired measurement data.

  • Real-time polymerase chain reaction-based genotyping assay for single nucleotide polymorphism
    Publication number: 20060134689
    Abstract: The present invention provides fluorescence-based real-time PCR assays for the rapid detection of single nucleotide polymorphisms (SNPs). The genotyping assay can be used to detect SNPs of a number of genes of interest that include, but are not limited to, the human multidrug resistance gene (MDR1) single nucleotide polymorphisms C3435T and G2677T, and cytochrome P-450 3A5 single nucleotide polymorphisms CYP3A5*3 (A22893G) and CYP3A5*6 (G30597A).
