  • Patent number: 10939887
    Abstract: A system and method of x-ray imaging includes obtaining a plurality of x-ray projection images of a patient. At least one object in the plurality of x-ray projection images is identified. A priori information of the identified at least one object is obtained. A three dimensional volume is reconstructed from the plurality of x-ray projection images. The a priori information is used to refine the acquisition of x-ray projection images or presentation of the three dimensional volume.
    Type: Grant

  • Patent number: 9770217
    Abstract: Systems and methods are presented for evaluating a dental condition. A first digital representation of at least a portion of an oral cavity of a first patient is compared to a second digital representation of the oral cavity of the same patient. The first digital representation is representative of the oral cavity of the first patient at a first time and the second digital representation is representative of the oral cavity of the first patient at a second, later time. At least one clinically-significant difference between the first digital representation and the second digital representation are automatically identified and the first digital representation is displayed in a way that highlights the at least one clinically significant difference.
