Patent number: 7697576Abstract: Raman molecular imaging is used to differentiate between normal and diseased cells or tissue. For instance benign and malignant lesions of bladder and other tissues can be distinguished, including epithelial tissues such as lung, prostate, kidney, breast, and colon, and non-epithelial tissues, such as bone marrow and brain. Raman scattering data relevant to the disease state of cells or tissue can be combined with visual image data to produce hybrid images which depict both a magnified view of the cellular structures and information relating to the disease state of the individual cells in the field of view.Type: GrantFiled: November 30, 2004Date of Patent: April 13, 2010Assignee: Chem Image CorporationInventors: John S. Maier, Joseph E. Demuth, Jeffrey K. Cohen, Shona Stewart, Lindy A. McClelland

Patent number: 7330746Abstract: The invention relates to methods and devices for assessing one or more blood components in an animal. The present invention permits non-invasive assessment of blood components in a body structure containing blood and other tissue types by assessing multiple regions of a tissue surface for an optical characteristic of blood and separately assessing one or more optical (e.g., Raman or NIR) characteristics of the blood component for one or more regions that exhibit the optical characteristic of blood.Type: GrantFiled: June 7, 2005Date of Patent: February 12, 2008Assignee: Chem Image CorporationInventors: Joseph E. Demuth, Patrick J. Treado, John S. Maier, Jeffrey K. Cohen

Patent number: 7218822Abstract: The disclosure generally relates to a method and apparatus for a fiberscope. In one embodiment, the disclosure relates to a chemical imaging fiberscope for imaging and collecting optical spectra from a sample having at least one illumination fiber for transmitting light from a first an a second light source to a distal end of a fiberscope; a dichroic mirror disposed at said distal end of the fiberscope such that light from said first light source passes substantially straight through said mirror and light of a predetermined wavelength from said second light source is substantially reflected by said mirror toward said sample to thereby illuminate said sample; and at least one collection fiber for receiving light from said illuminated sample and transmitting the received light to an optical device.Type: GrantFiled: October 4, 2004Date of Patent: May 15, 2007Assignee: Chemimage CorporationInventors: Patrick J. Treado, Matthew Nelson, Joseph E. Demuth
