  • Patent number: 9844101
    Abstract: A microwave heater comprises a cylindrical housing having an inner surface defining an internal cavity. A microwave generator is secured adjacent a first end of the housing and received inside the internal cavity is a sample holder that comprises an annular base member positioned adjacent the first end has a central axis coinciding with a longitudinal axis of the housing. A first opening is formed along the central axis, an outlet of the microwave generator extending through the first opening along the central axis for emitting into the internal cavity electromagnetic waves centered at a given microwave wavelength. A circular support plate substantially parallel to the base member and concentric therewith, a cavity portion defined therebetween, is separated from the base member by a distance less than the given microwave wavelength for establishing a Transverse Magnetic (TM) 01 mode as a predominant resonance mode inside the cavity portion.

  • Patent number: 9784678
    Abstract: There is provided an improved method for enhancing fluorescence images of an object, such as a biological tissue, by selectively eliminating or reducing unwanted fluorescence from fluorophores other than the fluorophore of interest. The method is based on the measurement of the lifetime of fluorophores while preserving information related to the fluorescence intensity of the fluorophore of interest.

  • Publication number: 20120065519
    Abstract: There is provided a method and a system for collecting optical data for use in time resolved optical imaging wherein excitation light of a tunable wavelength is directionally propagated to impinge on a plurality of illumination points at the surface of a region of interest in a turbid media, comprising for example a biological tissue such as that comprised in small animals or in human organs. Light re-emitted with a different wavelength from a fluorescent marker present in the tissue is collected and directionally propagated towards a detector. A filter located in a path of the light rejects photons outside a fluorescence emission spectrum of the fluorescent marker while maintaining selectivity of the re-emitted light. The detector produces time resolved optical signals useful for optical image reconstructions.

  • Publication number: 20120025101
    Abstract: The present invention relates to a method of decomposition of a test sample into constituents thereof. The method proceeds by optically imaging the test sample to obtain a corresponding unknown time-domain resolved signal and decomposes the unknown time-domain resolved signal by comparing the unknown time-domain resolved signal with time-domain resolved reference signals. Furthermore, the method allows the determination of the presence or absence of constituents. Relative quantities may also be determined if sample material properties are known or taken into account. Lifetime decay of the constituents may also be estimated by handling effect of light diffusion in the test sample as time decay.

  • Patent number: 8084755
    Abstract: Methods and apparatuses for determining the depth and concentration of fluorophores in a turbid medium are disclosed. The method advantageously provides for a rapid estimation of the depth of the flurophore using characteristics of a temporal point spread function. The concentration of the flurophore can be determined using the method of the present invention by combining a calculated depth of the flurophore with a measurement of the intensity of the emitted fluorescence. The intensity can be accurately measured by the apparatus disclosed herein which combine back-reflection and trans-illumination geometries for the source of light injecting and detection.
