摘要:
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.

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.
摘要:
The present invention relates to systems and methods of field-based light scattering spectroscopy. These systems and methods provide for the diagnosis of tissue by measuring the size and distribution of cellular characteristics. Field based measurements provide phase information resulting from the interaction of scatterers within the material and the incident wavefront. These measurements can be used to provide three dimensional images of tissue.
摘要:
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.

摘要:
Removal of body tissue with a long pulsed lasers is achieved such that sufficient energy to remove tissue is transmitted to the desired body without damaging an optical fiber transmitting the laser radiation. Pairs of pulses having the same or different wavelengths are coupled to more effectively remove tissue from the surgical site.
