Abstract: PURPOSE: An X-line breast cancer diagnosis system and method are provided to enhance the reliability of a three-dimensional image which is re-constructed by revising a center position error and determined left and right tilt. CONSTITUTION: An X- line source(110) irradiates an X- line in the breast of a patient who is fixed by a breast fixing apparatus(120). The breast fixing apparatus fixes the breast of the patient in order to be perpendicular with a direction emitting the X- line. A detector(140) is composed of sensor pixels of a matrix type. The detector detects an X-line projection picture which passes through the breast of the patient from the X- line source. The detector detects the X-line projection picture from various angles by controlling an X- line irradiation angle by using a rotator(130). A control means(160) reconstructs a three-dimensional projection image of the breast of the patient based on the X-line projection picture of two dimension.
