  • Publication number: 20160275679
    Abstract: A medical image reconstruction system and method for correcting a CT image such that the CT image is located at the center of a three-dimensional (3D) space in order to overcome an error that would otherwise be formed due to an inaccurate position of a patient during Obtaining CT images. After the 3D spatial positions of a 3D medical image are corrected using 3D medical image data, a trajectory of a dental arch is detected. A two-dimensional (2D) medical image is created from the 3D medical image through automatic reconstruction on the basis of the detected trajectory of the dental arch.

  • Publication number: 20160203601
    Abstract: Disclosed is a method for restoring a scan image. The method includes the steps of: measuring a blurring function oversampled with respect to a slit image obtained through a slit inclined at a predetermined angle in a vertical or horizontal direction according to the predetermined angle; and restoring a scan image to increase a resolution of an interface of a subject in the scan image obtained by obtaining the subject using the measured blurring function. Computed tomography (CT) that applies image restoration by increasing sampling can secure a precise image for computer-aided design (CAD)/computer-aided manufacturing (CAM) additionally used in a system used when actually diagnosing a patient, and thus does not require additional expenses and equipment.
