Abstract: A system using cross polarization effects and an enhancement agent having citric or other similar alpha hydroxy acid to enhance confocal microscope reflectance images and particularly images of the nuclei of BCCs (basal cell carcinomas) and SCCs (squamous cell carcinomas) in the confocal reflectance images of excised tumor slices obtained during Mohs surgery by illuminating the tissue being imaged (a tumor slice) using polarized light. The reflected illumination is passed to a polarization analyzer, which passes the polarization component which is crossed with respect to the polarization of the illuminating light. The light from the analyzer is passed through the confocal aperture and detected. The section of the tissue either at the surface or within the tissue is scanned and the reflectance image is produced with enhanced visualization of the cellular or nuclear structure thereof thereby enabling determination of the extent of the tumor (cancerous cells) in the section. A method is also provided using the system for diagnosing cancerous cells in skin tissue.

Abstract: A system is provided having a clamping apparatus with first and second members, which are spaced apart from each other. An attachment mechanism is connected to the first member for attaching the apparatus to a confocal imaging system. This attachment mechanism has a surface with a window facing the tissue to be examined. Opposing this surface is a third member connected to the second member. A clamping mechanism includes the first and second members for clamping the tissue between the surface of the attachment mechanism and the surface of the third member, thereby stabilizing the tissue to the confocal imaging system. The window of the attachment mechanism presents the clamped tissue to the confocal imaging system.

Abstract: A confocal microscope for generating an image of a sample includes a first scanning element for scanning a light beam along a first axis, and a second scanning element for scanning the light beam at a predetermined amplitude along a second axis perpendicular to the first axis. A third scanning element scans the light beam at a predetermined amplitude along a third axis perpendicular to an imaging plane defined by the first and second axes. The second and third scanning element are synchronized to scan at the same frequency. The second and third predetermined amplitudes are percentages of their maximum amplitudes. A selector determines the second and third predetermined amplitudes such that the sum of the percentages is equal to one-hundred percent.
