发明名称 Method and apparatus for detection of caries
摘要 A method for obtaining an image of tooth tissue directs incident light toward a tooth, wherein the incident light excites a fluorescent emission from the tooth tissue. Fluorescence image data is obtained from the fluorescent emission. Back-scattered reflectance image data is obtained from back-scattered light from the tooth tissue. The fluorescence and back-scattered reflectance image data are combined to form an enhanced image of the tooth tissue for caries detection.

主权项 1. A method for calibrating an imaging apparatus for teeth comprising: (a) obtaining a spectral measurement from at least one light source; (b) obtaining a spectral measurement from a fluorescent emission generated from a tooth in response to said at least one light source; (c) measuring the spectral response of a camera; and (d) generating scalar multiplier values to be used in image processing, according to the spectral measurements made in steps (a), (b), and (c), where the image processing comprises, accessing fluorescence image data obtained from a fluorescent emission excited by incident light directed toward a tooth,multiplying the fluorescence image data value by a first scalar multiplier according to the spectral measurements made in steps (b) and (c) to form a first value,accessing back-scattered reflectance image data from the tooth tissue obtained from back-scattered light,multiplying the back-scattered image data value by a second scalar multiplier according to the spectral measurements made in steps (a) and (c) to form a second value,adjusting the multiplied fluorescence image data with the multiplied back-scattered reflectance image data to form an enhanced image of the tooth tissue.
