摘要： A method for obtaining an image of tooth tissue directs incident light toward a tooth (20), wherein the incident light excites a fluorescent emission from the tooth tissue. Fluorescence image data (50) is obtained from the fluorescent emission. Back-scattered reflectance image data (52) 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 (64) of the tooth tissue for caries detection.

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： A method is disclosed for processing of images to detect dental caries, that includes the following steps. Directing incident light (16) toward a tooth (20), where this light excites a fluorescent emission from the tooth. Obtaining a fluorescence image (35) from the fluorescent light component (19), and obtaining a reflectance image (34) from the back-scattered light (18) from the tooth. Applying a color balance operation to the reflectance image. Removing the specular reflectance components from the color balanced reflectance image (82) to give a back-scattered reflectance image (50). Registering the fluorescent image with the back-scattered reflectance image. Combining the registered fluorescent image (115) with the back-scattered reflectance image to provide a diagnostic image (52).

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 forming an enhanced image of tooth tissue for caries detection obtains fluorescence (50) and reflectance (52) image data from a tooth (20). Each pixel in the fluorescence image data is combined with its corresponding pixel in the reflectance image data by subtracting an offset to the reflectance image data value to generate an offset reflectance image data value, and then computing an enhanced image data value according to the difference between the fluorescence image data value and the offset reflectance image data value, whereby the enhanced image (64) is formed from the resulting pixel array of enhanced image data values.

摘要： An apparatus for intraoral imaging has an intraoral camera that defines a field of view with a first dimension and a second dimension orthogonal to the first dimension. A projector has a laser diode energizable to emit a light beam; a collimator in the path of the emitted light beam; first beam-shaping optics disposed to shape the collimated light beam in the second dimension to form a linear light pattern; focusing optics disposed to focus the shaped collimated beam at a focal plane; and a scanner that is disposed substantially at the focal plane and that is energizable to scan the formed linear light pattern along the second dimension to successive positions of the field of view. A control logic processor coordinates energizing the laser diode and scanner with image capture by the intraoral camera.
