CT MARKER AND GENERATION METHOD OF THREE-DIMENSIONAL TOMOGRAPHIC IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a marker for three-dimensional tomography capable of providing an image with an accurate dimension when taking radiography.

SOLUTION: This marker is used for acquiring oral-cavity region tomographic data of an oral cavity region with its placed in the oral cavity region of a patient and acquiring profile data of a tooth row model with the tooth row model of the patient disposed thereon, and three-dimensional tomographic image is generated from the oral region tomographic data and the profile data with defining the position of the marker as the reference, wherein the marker consists of a mixing material of X-ray contrast and plastic.
