    Abstract: Exemplary quantitative susceptibility mapping methods, systems and computer-accessible medium can be provided to generate images of tissue magnetism property from complex magnetic resonance imaging data using the Bayesian statistical approach. The likelihood is constructed directly using the complex data. A prior is constructed from matching structures or information content in known morphology. The quantitative susceptibility map can be determined by, e.g., maximizing the posterior. Thus, according to the exemplary embodiment, system, method and computer-accessible medium can be provided for determining information associated with at least one structure.

  • Publication number: 20150144791
    Abstract: A method and analyser for identifying, verifying or otherwise characterising a sample involves emitting electromagnetic radiation in at least one beam at a sample. The electromagnetic radiation includes at least two different wavelengths. A sample detector detects affected electromagnetic radiation resulting from the emitted electromagnetic radiation affected by the sample and provides output representing the detected affected radiation. A processor determines sample coefficients from the output and identifies, verifies or otherwise characterises the sample using the sample coefficients and training coefficients determined from training samples. The coefficients reduce sensitivity to a sample retainer variation and/or are independent of concentration.

    Abstract: Provided is a terahertz wave generator having the following structural feature in a plane perpendicular to an optical propagation direction of an optical waveguide. Specifically, 0<r1<r2 is satisfied, where r1 represents a radius of curvature of a terahertz wave emitting plane of a coupling member at a point A at which a line extending from the optical waveguide in the normal direction to a surface of a substrate crosses the terahertz wave emitting plane of the coupling member, and r2 represents a radius of curvature of a wavefront of a terahertz wave at the same point A. Here, r1 has a positive value when being convex in a propagation direction of the terahertz wave.

  • Patent number: 9029775
    Abstract: An apparatus for analyzing, identifying or imaging an target including first and second laser beams coupled to a pair of photoconductive switches to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz focused on, and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a phase modulator in the path of one laser beam allows the constructive or destructive interference of the signals on the detector as the laser beams are swept in frequency to be adjusted to achieve greater resolution in one or more selected frequency bands.

  • Publication number: 20150115159
    Abstract: In some embodiments, the present invention provides methods of detecting strain associated with an object by: (1) irradiating a composition that has been applied to the object, where the composition comprises semiconducting single-walled carbon nanotubes; (2) measuring an emission from the irradiated composition, where the emission comprises near infrared emission; and (3) correlating the near infrared emission to the presence or absence of strain associated with the object. In some embodiments, the aforementioned steps occur without physically contacting the object or the composition. In some embodiments, the aforementioned steps occur without utilizing Raman spectroscopy. Further embodiments of the present invention also include a step of applying the composition to the object.

    Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

  • Patent number: 8969806
    Abstract: A drug inspection device and method for distinguishing tablets that have different amounts of active pharmaceutical ingredients and are indistinguishable in appearance. The device focuses on a tablet packaging process for tablets containing different amounts of active pharmaceutical ingredients, every row or every pocket, having housed therein a plurality of tablets, is used for conveyance. A beam having near-infrared light irradiates the tablets, a spectroscope receives reflected light, a near-infrared imaging unit captures a spectrum obtained through dispersion of the reflected light by the spectroscope and generates image data, and a control unit processes the image data and performs an operation for distinguishing the types of tablets. The control unit controls the near-infrared imaging unit to perform image capture at least once on the tablets included in the one row, to compute average spectrum data per tablet, and to distinguish the type of tablet based on the average spectrum data.
