摘要： 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.
