Abstract

A system and method for enhancing images of ex-vivo or in-vivo tissue produced by confocal microscopy, optical coherence tomography, two-photon microscopy, or ultrasound, is provided by applying to the tissue a solution or gel having an effective concentration of citric or other alpha-hydroxy acid which enhances tissue structures, such as cellular nuclei, in such images. Such concentration may be 3-20% acid, and preferably 5% acid.

Claims (29)

1. A system for enhancing images of in-vivo skin tissue comprising:

an imager producing one or more microscopic sectional images of in-vivo skin tissue; and

an image enhancing agent having an effective concentration of alpha-hydroxy acid that increases backscatter of one or more structures being imaged by said imager when said agent is applied to said in-vivo skin tissue.

2. The system according to claim 1 wherein said imager is a confocal microscope.

3. The system according to claim 1 wherein said imager is operative by one of optical coherence tomography, two-photon microscopy, and ultrasound.

4. The system according to claim 1 wherein said alpha-hydroxy acid is a solution or gel in water in the concentration of 3-20% acid to water.

5. The system according to claim 1 wherein said alpha-hydroxy acid is in a solution or gel in the concentration of 5% acid to water.

6. The system according to claim 1 wherein said alpha-hydroxy acid is citric acid.

7. The system according to claim 1 further comprising means for preparing tissue to expose deeper layers of said skin tissue.

8. The system according to claim 1 wherein said tissue has upper layers and lower layers, and said system further comprises tape for stripping said upper layers to expose said lower layers.

9. The system according to claim 1 wherein said alpha-hydroxy acid is in one of a solution or gel on said in-vivo tissue being imaged.

10. A system for enhancing images of ex-vivo tissue comprising:

an imager producing one or more microscopic sectional images of ex-vivo tissue; and

an image enhancing agent having an effective concentration of alpha-hydroxy acid that increases backscatter of one or more structures being imaged by said imager when said agent is applied to said ex-vivo tissue.

11. The system according to claim 10 wherein said imager is a confocal microscope.

12. The system according to claim 10 wherein said imager is operative by one of optical coherence tomography, two-photon microscopy, and ultrasound.

13. The system according to claim 10 wherein said alpha-hydroxy acid is a solution or gel in water in the concentration of 3-20% acid to water.

14. The system according to claim 10 wherein said alpha-hydroxy acid is in a solution or gel in the concentration of 5% acid to water.

15. The system according to claim 10 wherein said ex-vivo tissue is skin tissue.

16. The system according to claim 10 wherein said alpha-hydroxy acid is citric acid.

17. The system according to claim 10 wherein said alpha-hydroxy acid is in one of a solution or gel on said ex-vivo tissue being imaged.

18. An apparatus for enhancing images of cells comprising:

a microscope producing optically formed sectional images of tissue having the cells; and

an image enhancing agent applied to said tissue being imaged, said image enhancement agent comprising alpha-hydroxy acid that is sufficient in concentration to increase backscatter of light from one or more structures of the cells being imaged by said microscope which when applied by exposing said tissue in response to said alpha-hydroxy acid in and of itself enhances contrast of nuclei in the cells of the tissue in said images.

19. The apparatus according to claim 18 wherein said tissue is in-vivo tissue.

20. The apparatus according to claim 18 wherein said tissue is ex-vivo tissue.

21. The apparatus according to claim 18 wherein said microscope is operative by one of confocal microscopy, optical coherence tomography, or two-photon microscopy.

22. The apparatus according to claim 18 wherein said alpha-hydroxy acid is citric acid.

23. The apparatus according to claim 18 wherein said alpha-hydroxy acid is a solution or gel in 3-20% concentration.
