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.

Abstract: Disclosed herein is a method and apparatus for operating an X-ray image processing system of creating a panoramic image based on three-dimensional (3D) Computed Tomography (CT) image data and displaying the panoramic image on the display unit, receiving a part of an object to be measured in the panoramic image through the input unit, and calculating an actual 3D length of the part of the object based on depth information of the CT image data and displaying the actual 3D length on the display unit. The part of the object can be selected by the user to measure a length of a desired part.

Abstract: The present invention relates to a method and apparatus for detecting dental caries and an X-ray imaging apparatus and, more particularly, a method and apparatus for detecting dental caries and an X-ray imaging apparatus that can automatically detect occurrence and the degree of progress of caries by processing dental X-ray images.

Abstract: Disclosed is an apparatus and method for analyzing a radiography position error or a radiography condition error or both on basis of an x-ray radiograph. The apparatus includes an error data output unit outputting error data indicating that a radiography position or a radiography condition or both are incorrect by analyzing the X-ray radiograph; and an error data record unit recording the error data, wherein the error data output unit includes at least one of: a horizontal alignment error analysis unit analyzing a horizontal alignment error; a vertical alignment error analysis unit analyzing a vertical alignment error; a canine tooth alignment error analysis unit analyzing a canine tooth alignment error; an irradiation condition selection error analysis unit analyzing an irradiation condition selection error; a lead apron wearing error analysis unit analyzing a lead apron wearing error; and a Frankfort line alignment error analysis unit analyzing a Frankfort line alignment error.

Abstract: The disclosure is related to processing volume data of a volume rendered image. In particular, volume data is processed to clearly show a feature region in the volume rendered image. Such processing may include obtaining volume data for producing a volume rendered image from a third entity, generating feature data associated with a feature region in the volume rendered image using the obtained volume data, generating threshold data by setting a predetermined threshold value associated with the feature data, performing a thresholding process on the volume data using the generated threshold data, and emphasizing the feature region by processing the thresholding-processed volume data using the threshold data.
