| 20080227142 | Invasive chemometry - The invention relates to methods and devices for assessing one or more components of a selected tissue in an animal. The present invention permits non-invasive assessment of tissue components in a body structure containing multiple tissue types by assessing multiple regions of the animal's body for an optical characteristic of the tissue of interest and separately assessing one or more optical (e.g., Raman or NIR) characteristics of the tissue component for one or more regions that exhibit the optical characteristic of the tissue of interest. | 09-18-2008 |
| 20080297789 | Raman Spectral Analysis of Pathogens - A method of ablating a viable biological pathogen in a sample. A viable biological pathogen in a portion of the sample is identified by irradiating the sample; assessing radiation scattered from the sample for radiation that exhibits a Raman shift characteristic of the viable biological pathogen, and delivering an ablating agent to the identified portion. | 12-04-2008 |
| 20080316468 | SYSTEM AND METHOD FOR THE DEPOSITION, IMAGING, DETECTION AND IDENTIFICATION OF THREAT AGENTS - A system and method for depositing a sample of a threat agent onto a substrate. The deposition of the threat agent onto the substrate is visually observed by analyzing the elastic scattered photons produced by the threat agent using elastic scatter imaging to form an image of the threat agent on the substrate, wherein depositing of the threat agent is substantially coincident in time with visually observing of the deposition of the threat agent. | 12-25-2008 |
| 20090002698 | SYSTEM AND METHOD FOR THE ELECTROSTATIC DETECTION AND IDENTIFICATION OF THREAT AGENTS - A system and method for detecting aerosol threats comprising electrostatic collection and deposition of a threat agent onto a substrate. The threat agent deposited on the substrate is illuminated with a plurality of photons to thereby produce Raman scattered photons. The Raman scattered photons are analyzed in order to identify the threat agent. | 01-01-2009 |
| 20090021730 | METHOD AND APPARATUS FOR SUPER MONTAGE LARGE AREA SPECTROSCOPIC IMAGING - The disclosure relates to Method and Apparatus for Super Montage Large area Spectroscopic Imaging. In one embodiment of the disclosure, a method for producing a spectroscopic image of an object includes the steps of (a) irradiating the object with light to thereby produce from the object scattered and/or emitted (interchangeably “scattered”) light for each of a plurality of wavelengths; (b) producing separately for each of the plurality of wavelengths a plurality of substantially contiguous sub-images of the object; (c) compensating for spatial aberrations in ones of the sub-images for a select one of the plurality of wavelengths; (d) compensating for intensity aberrations between ones of the substantially contiguous sub-images for one of the plurality of wavelengths; and (e) combining the sub-images for the select one wavelength to thereby produce said spectroscopic image of the object. | 01-22-2009 |
| 20090086203 | Method for Correlating Spectroscopic Measurements with Digital Images of Contrast Enhanced Tissue - A system and method of correlating Raman measurements with digital images of a sample so to classify the sample's disease state. A spectroscopic data set is obtained for the sample positioned in the field of view of a spectroscopic device. With the sample removed from the field of view, the sample is treated with a contrast enhancing agent. The treated sample is repositioned in the spectroscopic device's field of view and a digital image of the treated sample is obtained. The 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. For the spectroscopic data set of the sample, the database is searched to identify a spectroscopic data set, of a known sample having well characterized pathology, which matches the sample's spectroscopic data set. | 04-02-2009 |
| 20090122309 | Raman Spectral Analysis of Pathogens - A method of assessing occurrence of a plant pathogen in a sample. The method comprises irradiating the sample and assessing radiation scattered from the sample for radiation that exhibits a Raman scattering characteristic of the pathogen. Detection of scattered radiation that exhibits a Raman shift characteristic of the pathogen is an indication that the pathogen occurs in the sample. | 05-14-2009 |
| 20090147242 | SYSTEM AND METHOD FOR THE COINCIDENT DEPOSITION, DETECTION AND IDENTIFICATION OF THREAT AGENTS - A system and method for depositing a sample of a threat agent is deposited onto a substrate. The threat agent is identified substantially coincident in time with the depositing of the sample of the threat agent onto the substrate. | 06-11-2009 |
| 20100034743 | Raman Characterization of Transplant Tissue - A system and method for determining a disease state and clinical outcome of a sample. A sample is illuminated to produce Raman scattered photons, the Raman scattered photons are assessed to generate a Raman spectroscopic data set representative of the sample, wherein said Raman spectroscopic data set comprises at least one of: a Raman spectra of the sample and a spatially accurate wavelength resolved Raman image of the sample; the Raman spectroscopic data set is evaluated using a chemometric technique to classify the disease state of the sample as: acute, chronic, incipient, or none. In one embodiment, the chemontric technique is principle component analysis. In another embodiment, the sample is obtained prior to transplantation and analysis can determine the likelihood of rejection by a host. | 02-11-2010 |
| 20100081127 | System and Method of Chemical Imaging Using Pulsed Laser Excitation and Time-Gated Detection to Determine Tissue Margins During Surgery - System and method for differentiating tissue margins in a biological sample using pulsed laser excitation and time-gated detection. A region containing a biological tissue is irradiated with substantially monochromatic pulsed laser light to thereby produce Raman scattered photons. The Raman scattered photons are detected using time-gated detection to thereby obtain a Raman spectroscopic image from the irradiated region characteristic of either a neoplastic portion or a non-neoplastic portion of the region containing the biological tissue. A boundary between a neoplastic portion and a non-neoplastic portion is differentiated and the boundary location in the Raman spectroscopic image is displayed. | 04-01-2010 |
