摘要： A method and apparatus are provided for a swept source optical coherence tomography (OCT) system utilizing a fast scanning mechanism in the sample arm and a slowly swept light source. The position data is collected rapidly while the wavelength of the source is swept slowly. The system reduces the sweep speed requirements of the light source enabling higher power, greater imaging range, and linear sweeps of the source frequency. The OCT components (or most of them) may be implemented within a hand held imaging probe. In operation, a triangulation scan may be used to orient the imaging probe with respect to a fixed coordinate system; preferably, OCT data captured by the device is then transformed to that same orientation with respect to the fixed coordinate system to improve the scanning results.

摘要： A dental CAD/CAM application generates a 3D model representing a patient's dental anatomy. This model may be a 3D surface. The surface may also be textured with either a monochrome or color image superimposed. The display routine that is used to display the 3D model is enhanced to adjust the contrast in the region of a displayed mouse pointer (or other input device) as a user explores the display image. When this feature is activated and the mouse pointer positioned, preferably the texturing on the 3D model is recomputed in that local area and redisplayed showing greater contrast and detail. Preferably, the contrast is increased from a center to an edge of the area of contrast. Having the texturing of the model being improved and highlighted around the margin is desirable, as it allows the user to see more easily where the margin is located.

IPC分类号： A61B5/00
摘要： An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device provides for more efficient transmission and capture of images. It integrates OCT scanning with RGB-based scanning. In operation, the device is used for recording topological characteristics of teeth, dental impressions, or stone models by digital methods and for use in CAD/CAM of dental restorative prosthetic devices. To that end, the RGB-based scan obtains surface data (e.g., a margin), while the OCT scan penetrates the surface. The two scanners operate from within the same physical housing and preferably at the same time such that only one scanning pass (to obtain all necessary data) is required. The 3D data obtained from the OCT scan is registered with the 3D data obtained from the RGB-based scan by virtue of being captured using a common return path. Preferably, the 3D surface data is used to align the volume data, such that the OCT scan operates over a much sparser scanning volume than would otherwise be required if the OCT scan were carried out separately. In this manner, there is less stitching of data required to build the output images, thereby enabling a “one-pass” operation.

摘要： A technique to enable an existing monochrome camera in an intra-oral scanner to capture color images without making hardware changes to the camera. This operation is achieved by retrofitting a “tip” assembly of the scanner with red, green and blue light emitting diodes (LEDs), and then driving those diodes to illuminate the scene being captured by the scanner. Electronics in or associated with the scanner are operative to synchronize the LEDs to the frame capture of the monochrome camera in the device. A color image is created by combining the red-, green- and blue-illuminated images. Thus, color imagery is created from a monochrome camera and, in particular, by illuminating the screen with specific colors while the camera captures images. In this manner, single colored images are captured and combined into full color images. The system captures the color images with full resolution and sensitivity, thus producing higher quality full color images.
