PURPOSE: A tomography system including a small X-ray source is provided to effectively obtain a high quality radiation 3D reconstructed image by taking a photograph of an object while rotating a gantry in a predetermined angle to obtain image information. CONSTITUTION: A small vacuum chamber(20) is separated from an X-ray detector(10). A circular gantry unit(30) fixes the X-ray detector and the small vacuum chamber. The circular gantry unit is rotationally formed. A unit X-ray source is attached in the small vacuum chamber. An object and an X-ray filter are located between the X-ray detector and the small vacuum chamber. [Reference numerals] (60) Controller |
