摘要： The disclosure provides for a system and method for detecting a threat agent. A sample is illuminated to produce photons Raman scattered and emitted by the sample. The Raman scattered photons are collected using time-gated detection without collecting the emitted photons. A Raman spectroscopic data set is generated from said Raman scattered photons wherein said Raman spectroscopic data comprises at least one of a Raman spectrum and a Raman chemical image. The Raman spectroscopic data is assessed to thereby determine the presence or absence of a threat agent in the sample. The sample may be in a target area. The sample may be illuminated using a pulsed laser or an intensity modulated laser. The illumination source may be synchronized with a gating element that enables time-gated detection.

摘要： A method and system to differentiate a tissue margins during various medical procedures. A region containing a biological tissue is irradiated, with a substantially monochromatic light. Raman spectroscopic data is obtained from the irradiated region. A boundary between a neoplastic portion and a non-neoplastic portion, in the region containing the biological tissue, is differentiated by evaluating the Raman spectroscopic data for at least one Raman spectroscopic value characteristic of either the neoplastic portion or the non-neoplastic portion. The neoplastic portion is selected for physical manipulation based on the differentiation of the boundary between the neoplastic portion and the non-neoplastic portion.

摘要： A method and apparatus for determining the progress of a disease. A pre-determined vector space is determined where the vector space mathematically describes a reference set of wavelength resolved data at a plurality of time intervals. A sample containing at least one cell is irradiated with light. Target data is collected where the target data corresponds to at least one of light emitted from or scattered by the sample and includes a plurality of spatially accurate wavelength resolved measurements of light. The target data is transformed into the pre-determined vector space for each spatially accurate wavelength resolved measurement of light. A distribution of transformed points is analyzed in the plurality of pre-determined vector space. Based on the analysis, a transition of a disease condition of the sample is classified.

摘要： A method and system of differentially manipulating cells where the cells, suspended in a fluid, are irradiated with substantially monochromatic light. A Raman data set is obtained from the irradiated cells and where the data set is characteristic of a disease status. The data set is assessed to identify diseased cells. A Raman chemical image of the irradiated cells is also obtained. Based on the assessment and the Raman chemical image, the fluid in which the cells are suspended is differentially manipulated. The diseased cells are directed to a first location and other non-diseased cells are directed to a second location as part of the differential manipulation. The diseased cells may be treated with a physical stress, a chemical stress, and a biological stress and then returned to a patient from whom the diseased cells were obtained prior to the irradiation.

摘要： A system and method of correlating Raman measurements with digital images of a treated sample and using this correlation to classify the disease state of the sample. A spectroscopic data set is obtained for the sample positioned in the field of view of a spectroscopic device. The positional information about the field of view is stored. With the sample removed from the field of view, the sample is treated with a contrast enhancing agent. Using the stored positional information for the field of view, the treated sample is repositioned in the spectroscopic device's field of view. A digital image of the treated sample positioned in the field of view is obtained. The first spectroscopic data set is linked with the digital image by defining a transformation to map the image spatial coordinates of the digital image to the spectral spatial coordinates of the spectroscopic data. A database having a plurality of spectroscopic data sets, for samples having well characterized pathology, is provided. Each spectroscopic data set is linked to a corresponding digital image, and each spectroscopic data set is associated with the known sample. Each corresponding digital image is associated with the known sample treated with a contrast enhancing agent. For the spectroscopic data set of the sample, the database is searched to identify a spectroscopic data set, of a known sample, matching the sample's spectroscopic data set.
