A system for analyzing tissue includes a platform and an optical sensing unit coupled to the platform. The optical sensing unit has a detector and a plurality of light sources surrounding and electrically isolated from the detector. The optical sensing units obtain optical data for tissue analysis.

System for analyzing tissue

This disclosure provides a method of determining the viability of at least one cell via quantification of nicotinamide adenine dinucleotide (phosphate) (NAD(P)H), flavin adenine dinucleotide (FAD), and/or collagen. The method includes the steps of contacting the at least one cell with light having a wavelength of from 700 to 900 nm, using two photon excitation, or from 335 to 400 nm, using one photon excitation, to induce an optical response from the NAD(P)H, FAD, and/or collagen and measuring the optical response. The method also includes the step of quantifying one or more of an amount, spatial localization, and/or time-dependent response of the NAD(P)H, FAD, and/or collagen utilizing the optical response.

Multimodal optical spectroscopy systems and methods produce a spectroscopic event to obtain spectroscopic response data from biological tissue, either ex vivo or in vivo, and compare the response data with a model configured to correlate the measured response data and the most probable attributes of the tissue, thus facilitating classification of the tissue based on those attributes.

Multimodal spectroscopic systems and methods for classifying biological tissue

This invention relates to method and apparatus for collection of the complete fluorescence emission spectrum and the transient decay of a selected spectral band simultaneously with data acquisition times of less that one second. This invention is useful for studying human tissues and cells in vivo.

Fluorescence lifetime spectrometer (FLS) and methods of detecting diseased tissue

Multimodal optical spectroscopy systems and methods produce a spectroscopic event to obtain spectroscopic response data from biological tissue and compare the response data with preset criteria configured to correlate the measured response data and the most probable attributes of the tissue, thus facilitating classification of the tissue based on those attributes for subsequent biopsy or remedial measures as necessary.
