    摘要： A digital imaging system provides color information of an entire port wine stain or other skin condition with a single image in CIE L*a*b* color space (L*, a*) derived from RGB pixel data (R, G, B). Cross-polarization optics produce marked reduction in specularly reflected light in the images. A patient positioning device allows for repeatable positioning of the patient's head or body portion. The digital nature of the system provides a near real-time mapping of melanin and erythema or other skin chromophore metrics. The cross-polarized diffuse reflectance color digital imaging system obtains subsurface skin color information and acquisition of facial images in a reproducible fashion at a fixed distance from an illumination source at optimized angles of view depending on the region of interest being imaged.

    摘要： The invention includes a noninvasive method for characterizing dental pulpal vitality of a tooth including the steps of irradiating the tooth with at least partially coherent light, and speckle imaging to provide quantitative feedback to an end user of pulpal blood flow in the tooth, and the tangible records made by such a method. The invention also includes an apparatus for noninvasively characterizing dental pulpal vitality of a tooth comprising a source of at least partially coherent light for irradiating the tooth characterized by a speckle pattern, optics for directing the at least partially coherent light onto the tooth, including a corresponding pulpal cavity within the tooth, a detector for detecting transmission of the at least partially coherent light through the tooth, and a processor coupled to the detector speckle imaging to provide a quantitative feedback of pulpal blood flow in the tooth.
