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.

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 for imaging a tooth having a light source with a first spectral range and a second spectral range. A polarizing beamsplitter (18) 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 first and second polarization states are orthogonal. A first lens (22) in the return path directs image-bearing light from the tooth, through the polarizing beamsplitter (18), toward the sensor (68), and obtains image data from the redirected 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. Control logic enables the sensor to obtain either the reflectance image or the fluorescence image.

摘要： An intra-oral imaging apparatus having a fringe pattern generator energizable to emit a fringe pattern illumination having a predetermined spatial frequency, with light in the approximate 350-500 nm range. A polarizer in the path of the fringe pattern illumination has a first polarization transmission axis. A projection lens is disposed to direct the polarized fringe pattern illumination as incident illumination toward a tooth surface. An imaging lens is disposed to direct light reflected and scattered at the tooth surface along a detection path. An analyzer is disposed along the detection path, having a second polarization transmission axis. A detector disposed along the detection path obtains image data from the light provided through the analyzer. A control logic processor is responsive to programmed instructions and actuable to adjust the intensity over one or more portions of the fringe pattern illumination according to the image data obtained from the detector.

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.
