Patents by Inventor Vadim Backman

Vadim Backman 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
    Patent number: 6624890
    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: Grant
    Filed: May 24, 2002
    Date of Patent: September 23, 2003
    Assignee: Massachusetts Institute of Technology
    Inventors: Vadim Backman, Ramachandra R. Dasari, Rajan Gurjar, Irving Itzkan, Lev Perelman, Michael S. Feld

  • Fluorescence, reflectance and light scattering spectroscopy for measuring tissue
    Publication number: 20020143243
    Abstract: The present invention utilizes a plurality of spectroscopic techniques to measure characteristics of tissue useful in the diagnosis of disease. Fluorescence, reflectance and light scattered spectra can be measured and processed to determine the size, distribution and/or composition of tissue. The methods and systems can be used particularly in the early detection of carcinoma within tissue in vivo and in vitro.

  • Measuring tissue morphology
    Patent number: 6091984
    Abstract: The present invention relates to systems and methods for measuring one or more physical characteristics of material such as tissue using optical radiation. The system can use light that is scattered by a tissue layer to determine, for example, the size of nuclei in the tissue layer to aid in the characterization of the tissue. These methods can include the use of fiber optic devices to deliver and collect light from a tissue region of interest to diagnose, for example, whether the tissue is normal or precancerous.
