    摘要： A method of comparing the size of a feature in sequential X-ray images includes the steps of: forming first and second sequential X-ray images including an image of the feature, an image of a first target located directly adjacent the feature and an image of a second target located between the object and an X-ray detector; calculating scale factors for the first and second X-ray images based on the relative sizes of the images of the first and second targets in the X-ray images; measuring the sizes of the feature in the first and second X-ray images; adjusting the measured sizes of the feature in the first and second X-ray images by the respective scale factors; and comparing the adjusted measured sizes. A computer program product for performing the method is also provided.

    摘要： A method for determining dental alignment of a 3-dimensional model of one or more teeth of a patient comprises the steps of: (a) obtaining a radiograph of the teeth of the patient; (b) obtaining a digital image from the radiograph indicative of the dental alignment of the teeth relative to a dental arch of the patient; (c) overlaying the 3-dimensional model of the teeth with the digital image obtained from the radiograph; (d) determining vertical and horizontal mis-alignment of the teeth in the 3-dimensional model relative to the digital image obtained from the radiograph; and (e) adjusting the 3-dimensional model to correct for the mis-alignment, thereby producing an adjusted 3-dimensional model of the teeth that is corrected for the vertical and horizontal alignment of the teeth relative to the dental arch.

    摘要： A portable intra-oral capture and display system, designed for use by a dental practitioner in connection with a patient seated in a dental chair, includes: a handpiece elongated for insertion into an oral cavity of the patient, where the handpiece includes a light emitter on a distal end thereof for illuminating an object in the cavity and an image sensor for capturing an image of the object and generating an image signal therefrom; a monitor interconnected with the handpiece, where the monitor contains electronics for processing the image for display and a display element for displaying the image, where the interconnection between the monitor and the handpiece includes an electrical connection for communicating the image signal from the image sensor in the camera to the electronics in the monitor; and a receptacle on the dental chair for receiving the monitor, wherein the receptacle conforms to the monitor such that the monitor may be withdrawn from the receptacle in order to allow the display element to be seen by the dental practitioner or the patient.

    摘要： An image registration method is described for X-ray imagery, in which specific views of the x-rays are provided to optimize tie point selection accuracy and efficiency. The first view maintains context during initial point selection. The second view provides a detailed view of each point pair, to allow for fine adjustment, while automatically presenting each point pair in sequence to the user. After the tie points are refined and the images are registered, a third view is provided which allows direct comparison of the registered images.
