Patents by Inventor Ramanchandra R. Dasari

Ramanchandra R. Dasari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polarized light scattering spectroscopy of tissue
    Publication number: 20020171831
    Abstract: The present invention relates to the use of polarized light to measure properties of tissue. More particularly, polarized light can be used to detect dysplasia in tissue as the polarization of back-scattered light from such tissues is preserved while the contribution of diffusely scattered light from underlying tissues can be removed. A fiber optic system for delivery and collection of light can be used to measure tissues within the human body.
    Type: Application
    Filed: May 24, 2002
    Publication date: November 21, 2002
    Applicant: Massachusetts Institute of Technology
    Inventors: Vadim Backman, Ramanchandra R. Dasari, Rajan Gurjar, Irving Itzkan, Lev Perelman, Michael S. Feld

  • Apparatus and methods of raman spectroscopy for analysis of blood gases and analytes
    Patent number: 5615673
    Abstract: The present invention relates to systems of methods of measuring selected analytes in blood and tissue using Raman spectroscopy to aid in diagnosis. More particularly, Raman spectra are collected and analyzed to measure the concentration of dissolved gases and other analytes of interest in blood. Methods include in vivo transdermal and continuous monitoring as well as in vitro blood analysis.
