X-RAY BREAST CANCER DIAGNOSTIC SYSTEM FOR CALIBRATING THE GEOMETRY USING PHANTOM AND METHOD THEREOF

摘要

PURPOSE: An X-ray based breast cancer diagnosing system and a method for the same are provided to obtain three dimensional projection images with the superior reliability by acquiring accurate data with respect to the structure of the system. CONSTITUTION: X-ray source(110) irradiates X-ray from the left side and the right side at the same angle. A phantom(150) is formed by three-dimensional rectangular through which the x-ray transmits. The phantom includes a plurality of bearings. A detector(140) detects image projected based on X-ray. A controlling unit(160) verifies the symmetrical characteristic with respect to two figures generated by the bearings.
