Filed:

Jan 2, 2003

Appl. No.:

10/336025

Inventors:

Marek Elbaum - Dobbs Ferry NY, US
Adam Jacobs - Woodcliff Lake NJ, US
Sunguk Keem - Norwood NJ, US

Assignee:

Electro Optical Sciences Inc - Irvington-on-Hudson NY

International Classification:

G06K 9/00

US Classification:

382128

Abstract:

Data corresponding to biological tissue or lesions imaged in a remote location are communicated automatically to a central location, where the data are analyzed using data and algorithms stored securely at the central location. A result of the analysis is communicated from the central location to the remote location. Payment to an entity associated with the central location is made for each image or set of images.

Abstract:

A method and apparatus for imaging teeth includes illuminating a surface of a tooth and electronically imaging the tooth from a non-illuminated surface of the tooth with an electronic camera. Automatic control of the intensity of illumination is preferably provided to avoid saturation of the camera. The camera may include a charge-coupled-device and the resulting digital images are preferably enhanced by wavelet analysis. If a video camera is used, the images may be digitized and then enhanced. Current images of the tooth may be compared to prior images of the same tooth to monitor changes in the tooth over time. The images can be used to detect dental caries and other dental conditions. A handpiece for illuminating the tooth and receiving the light passing through the tooth for reception by the camera in a reproducible manner, is also described.
