A skin testing and imaging station and corresponding method for capturing, displaying and analyzing images of a person and for testing the skin using a variety of probes includes a digital camera, a light source capable of providing at least two different wavelengths of light, a plurality of probes for conducting skin tests, a touch-screen display and a computer for controlling the components of the station. The apparatus selectively captures and displays a plurality of digital images using different wavelengths of illuminating light, e.g., using a plurality of flashes and filters, some of which may be adjustable to adjust the angle of incidence of the illuminating light on the subject. In video mode, the camera displays a real time image on the display facilitating a user to position a probe for testing any specific area of the skin. Preferably, the apparatus is self-serve, allowing any person to capture, review and analyze the images and skin data. Verbal and / or graphic instructions to a user aid in use of the station. An intuitive graphic user interface with thumbnail images is employed. Focus control, zoom and synchronized side-by side comparison of images are available.

An improved system for confocal imaging within dermal tissue of a patient is provided which minimizes instability in confocal images by reducing the relative motion of the tissue with respect to the confocal imaging optics of the system. The system includes a mechanism for maintaining an area of skin tissue under stress by application of force at the edges of the area, and an imaging head coupled to this mechanism for imaging the stressed skin. The mechanism includes a mechanical structure, such as a platen, brace, or attachment, which both supports the imaging head of the system and applies stress to a limited surface area of the tissue to minimize skin motion during confocal imaging.

An apparatus for skin imaging uses a combination of near-field and far-field skin images under different angles of illumination. The apparatus provides a tool that may be employed for rapid screening of the skin for lesions that may be indicative of skin diseases, in particular skin cancers such as melanoma.
