    摘要： In accordance with embodiments of the present technique, a combined modality imaging system includes a first imaging device of a first modality and a second imaging device of a second modality that is different from the first modality. The first and the second imaging devices are both adapted to interact with a contrast agent adapted to be received in a subject. The contrast agent includes an deformable particle that has a geometry that varies in response to an emission from the first imaging device. The deformable particle also includes a fluorescent component adapted to emit electromagnetic radiation that is detectable by the second imaging device and a quenching component separated from the fluorescent component at a distance based on the geometry and that which is adapted to absorb a portion of the electromagnetic radiation from the fluorescent component.

    摘要： A method and system for localization of fluorescence in a scattering medium such as a biological tissue are provided. In comparison to other optical imaging techniques, this disclosure provides for improved spatial resolution, decreased computational time for reconstructions, and allows anatomical and functional imaging simultaneously. The method including the steps of illuminating the scattering medium with an excitation light to excite the fluorescence; modulating a portion of the emitted light from the fluorescence within the scattering medium using an ultrasonically induced variation of material properties of the scattering medium such as the refractive index; detecting the modulated optical signal at a surface of the scattering medium; and reconstructing a spatial distribution of the fluorescence in the scattering medium from the detected signal.

    摘要： A method and system for adaptive acquisition of magnetic resonance imaging (MRI) data by initially performing an analysis of a set of samples using a wide range of spin-lattice relaxation time (T1) times, and spin-spin relaxation time (T2) times of the sample under magnetic resonance imaging, and ranking the level of impact each of those T1s and T2s has on inversion times (TIs) and echo times (TEs) respectively. The method and system create a look-up table based on the data generated, and then perform another measurement using a smaller number of T1s and T2s using a small number of TIs and TEs, and compare the results to the data in the look-up table in order to select the closest point in the look-up table.

    摘要： An illumination device comprising: an incoherent light source; a non-imaging light collection system disposed to collect light emitted by the light source; an electro-optic modulator that receives light collected by the light collection system and modulates its intensity; and a light delivery system that receives intensity-modulated light output by the electro-optic modulator and illuminates an area with diverging intensity-modulated light. High-powered incoherent, multi-spectral illumination sources, such as lamps or LED arrays, are used. Non-imaging light collection elements, such as fiber optic bundles, total internal reflection lens arrays or compound parabolic light concentrators, are used to reduce the divergence of the light source for efficient transmission of light through an electro-optic modulator.

    摘要： A method for enhancing contrast in fluorescence imaging is provided. The method comprises providing a patterned illumination source for illuminating one or more regions corresponding to a scan step, scanning at least a portion of a surface of a subject using a plurality of scan steps, acquiring image frames corresponding to two or more scan steps, deducting a background fluorescence from the image frames corresponding to the two or more scan steps to form one or more processed image frames, and reconstructing an image using one or more of the processed image frames.
