Claims
- 1. A method for determining if tissue is cancerous comprising:
- a. exciting a tissue to be examined with a beam of light, and
- b. comparing the visible native luminescence emitted from the tissue with the visible native luminescence emitted from tissue whose condition is known.
- 2. A method for determining if tissue is cancerous comprising:
- a. exciting a tissue to be examined with a beam of light.
- b. observing the visible native luminescence emitted from the tissue at least two wavelengths, and
- c. determining if the tissue is cancerous in accordance with said measurements.
- 3. A method for detecting cancerous tissue comprising:
- a. exciting a tissue to be examined with a beam of light that is substantially monochromatic, and then
- b. comparing the resulting native luminescence spectrum with the native luminescence spectra for native normal and cancerous tissue.
- 4. A method for detecting cancerous tissue comprising:
- a. exciting a tissue to be examined with a beam of light that is at least substantially monochromatic.
- b. measuring the intensity of the visible native luminescence emitted from the tissue at least two wavelengths, and
- c. determining if the tissue is cancerous in accordance with said measurements.
- 5. The method of claim 4 and wherein determining if cancerous tissue is present comprises determining the ratios in intensities at at least two wavelengths and then comparing the ratios with the ratios of intensities at the same wavelengths for normal tissue.
- 6. The method of claim 4 and wherein determining if cancerous tissue is present includes producing a signal corresponding to the ratio between the intensities at least two wavelengths and then displaying said signals.
- 7. The method of claim 4 and wherein determining if cancerous tissue is present comprises producing a signal corresponding to the difference in the intensity at at least two wavelengths.
- 8. The method of claim 4 and wherein determining if cancerous tissue is present comprises producing a signal corresponding to the difference in spectral profiles.
- 9. A method for detecting cancerous tissue comprising:
- a. exciting a tissue to be examined with a beam of monochromatic light.
- b. generating a luminescence spectrum native of light emitted by the tissue, and
- c. comparing the luminescent spectrum with a luminescent spectrum for a known normal tissue.
