Abstract: For dental and facial imaging, a source of x-rays (14) or other penetrating radiation and a detector (20) are mounted opposite one another on a rotatable gantry (28), so that the head of the patient can be positioned between the source (14) and the detector (20), with the axis of rotation (36) of the gantry passing through the patient's head. The detector is longer in one direction than in the perpendicular direction, generally rectangular, and is rotatable between a position in which the long axis is transverse to the axis of rotation of the gantry and a position in which the long axis is generally parallel to the axis of rotation of the gantry. The length of the detector along the long axis is sufficient for fully detailed computed CT when the long axis is transverse, and for full-face CT when the long axis is parallel.

Abstract: A system for removing artifacts caused by x-ray reflective materials from an x-ray image of a patient's teeth. The system includes an x-ray source, an x-ray detector that captures several x-ray images, and a surface scanner that captures a surface scan of the patient's teeth. An image processor generates three-dimensional models from the optical surface data and the CT volumetric data. The models are resized and oriented to be of the same scale and orientation and then overlaid to create a combined data set. Data points that extend beyond the surface of the patient's teeth in the surface model are identified and may be removed if it is determined that they are artifacts. An artifact-reduced CT model is then displayed.

Abstract: For dental and facial imaging, a source of x-rays (14) or other penetrating radiation and a detector (20) are mounted opposite one another on a rotatable gantry (28), so that the head of the patient can be positioned between the source (14) and the detector (20), with the axis of rotation (36) of the gantry passing through the patient's head. The detector or the source are mounted so they can translate and/or pivot horizontally or vertically. The gantry is angulated so that the source or the detector may not be at the same height relative to the patient's head. The gantry can telescope, moving the source and the detector closer together or further apart. The collimator changes dynamically with the motion of the gantry and/or the source and detector to scan a smaller portion of the scan field.

Abstract: A method and apparatus for locating an elongated object in a three dimensional data array are disclosed. A slice of data generally lengthways of the elongated object is selected. Points on the object in the selected slice are identified. Data including the points are transposed parallel to the slice and transversely to the elongated object to align the points in a direction parallel to the slice and transverse to the elongated object. A current slice is selected that is rotated around the length direction of the object relative to the previously selected slice. The identifying and transposing are repeated to align points on the object in a direction parallel to the current slice and transverse to the elongated object.

Abstract: In one embodiment of a method of and apparatus for correcting for scatter, an object, which may be the jaw of a dental patient, is subjected to x-rays or other penetrating radiation. An intensity distribution of the transmitted radiation is detected. A first array of voxel data representing the absorption of the radiation by the object is reconstructed from the detected intensity. A radiation scatter pattern is calculated by forward projection from the first array using one or more point spread functions. The detected intensity is corrected using the calculated radiation scatter pattern. A second array of voxel data representing the absorption of the radiation by the object is reconstructed from the corrected detected intensity.
