PROBLEM TO BE SOLVED: To provide dental panorama X-ray equipment having a means imaging an occlusion bite piece formed by previously embedding steel balls in portions changing a magnification ratio along the dentition, along with a subject and measuring and displaying intervals of the steel balls on image data; measuring the distance of every portion and displaying it on a monitor. SOLUTION: This dental panorama X-ray imaging equipment comprises a memory storage means imaging the occlusion bite piece formed by previously embedding the steel balls in portions changing the magnification ratio along the dentition, along with a subject, and measuring and storing the image data formed by imaging the steel balls of the occlusion bite piece; a display means displaying the stored image data; a measuring means measuring the intervals of the steel balls for the occlusion bite piece on the displayed image data; and a measured value correcting means correcting the measured value by comparing it with reference value data of the steel balls preset for correcting the measured value. This equipment can measure the distance of every portion and display it on the monitor. COPYRIGHT: (C)2005,JPO&NCIPI
