  • Enhancing contrast in biological imaging
    Patent number: 6593101
    Abstract: Methods for enhancing contrast during imaging to assess cell and nuclear morphology of a sample. A contrast agent such as acetic acid, toluidine blue, hypertonic saline, hypotonic saline, Lugol's iodine, an absorbing dye, a liposome, or a contrast agent linked to a marker are applied to a sample. The sample is analyzed with an imaging device to create image data, and the sample is diagnosed using the image data.
    Type: Grant
    Filed: March 28, 2001
    Date of Patent: July 15, 2003
    Assignee: Board of Regents, The University of Texas System
    Inventors: Rebecca R. Richards-Kortum, Andrés F. Zuluaga, Rebekah Drezek, Colin Smithpeter, Tom Collier

  • Acetic acid as a contrast in reflectance confocal imaging of tissue
    Patent number: 6187289
    Abstract: A method for using acetic acid as a contrast agent during reflectance confocal imaging of normal and neoplastic tissue, particularly epithelium. In one aspect, the invention includes a method of using acetic acid as a contrast agent for confocal imaging of cells, including applying acetic acid to the diagnostic tissue sample in sufficient concentration to induce a small scale alteration of the index of refraction of nuclei in the cells; and imaging such cells using a reflectance confocal imaging system.
