First Claim
Patent Images
1. A method of identifying tissue comprising the steps of determining the infrared spectrum of a tissue sample over a range of frequencies in at least one frequency band, and comparing the infrared spectrum of said sample with a library of stored infrared spectra of known tissue types by visual comparison or using pattern recognition techniques to find the closest match.

7. A method of identifying non-malignant tissue, comprising the steps of determining the infrared spectrum of a tissue sample over a range of frequencies in at least one frequency band;
- comparing said infrared spectrum with a library of infrared spectra of known normal tissue types by visual comparison or using pattern recognition techniques; and
identifying the sample as non-malignant if it substantially matches one of said know tissue types. - View Dependent Claims (8, 9, 10)

11. An apparatus for identifying tissue comprising:
-
a) a first memory for storing the infrared spectra of a plurality of known tissue types in at least one frequency band; b) an infrared spectrometer for determining the infrared spectrum of a tissue sample over a range of frequencies in at least one frequency band; c) a second memory for storing said infrared spectrum of said tissue sample; d) a processor for comparing the infrared spectra stored in said first and second memories using pattern recognition techniques to find the closest match; and e) a display device for displaying the results of said comparison to permit identification of said sample tissue. - View Dependent Claims (12, 13)
