چکیده انگلیسی
Dual energy X-ray CT was carried out with synchrotron radiation at BL20B2 beam line of JASRI/SPring-8. The X-ray beams were vertically magnified by employing an asymmetry Bragg reflection geometry. The field size was about 25 mm×250 mm at the end of the beam line. Porcine eyes and brain and water were used as samples. The DXCT provided the highly accurate information on an electron density; the electron density of water was in agreement of about 0.6% with the theoretical value. Images of the electron density and an effective atomic number had good quality sufficient for medical applications.
