摘要: An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.

摘要: A method for obtaining an image of a tooth obtains an area image of the tooth (20) surface and identifies a region of interest from the area image by positioning a marker (146) on the area image. The marker (146) corresponds to at least a portion of the region of interest and identifies a scanning area. An optical coherence tomography (OCT) image is then obtained over the scanning area.

摘要: An apparatus (10) for obtaining an image of a tooth (20) includes an image sensor and a white light source (12) providing broadband polychromatic light and an ultraviolet light source providing narrow-band light. A combiner (15) directs broadband polychromatic light and narrow band light along a common illumination path to illuminate the tooth. A polarization beamsplitter (18) directs polarized light from the illumination path along an optical axis (216). An optical coherence tomography (OCT) imaging apparatus (70) splits the low coherence light into a sample path and a reference path and a dichroic element (78) directs the polarized illumination and the sample path low coherence light along the optical axis. An image processor (100) identifies a region of interest according to either a white light image (124), a fluorescent light image (120), or both and the OCT imaging apparatus obtains an OCT image over the region of interest.

摘要: A method for caries detection uses an image capture device (30, 32) to obtain fluorescence image data from the tooth (20) by illuminating the tooth to excite fluorescent emission. A first enhanced image of the tooth is then obtained by illuminating the tooth at a first incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. A second enhanced image of the tooth is then obtained by illuminating the tooth at a second incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. The first and second enhanced images are then analyzed to select and display the best-contrast image. This method provides high contrast images for carious regions (58) on all tooth surfaces.
