    Abstract: A method and apparatus for generating a panoramic image of part of a target, comprises providing a scanner having a source of penetrating radiation facing a detector having an array of sensors for the penetrating radiation. The target is positioned between the source of penetrating radiation and the detector, and scanned with relative rotation of the scanner and the target. Radiation received at a plurality of the sensors spaced apart in the circumferential direction of the relative rotation is separately recorded. A panoramic image is generated by combining for each pixel of the panoramic image outputs from different sensors at different times during the relative rotation, the combined outputs being selected to represent rays of radiation passing through a point on a defined curve. The generated panoramic image and a graphical representation of the defined curve are displayed. Instructions are received from a user to alter the defined curve. The generating and displaying of the panoramic image are repeated using the altered curve.

    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.

    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: 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.
