Using a broad band, high parallelity and extremely high brilliance of synchrotron radiation x-rays a variety of medical imaging has been proposed. Two types of x-ray imaging systems using an angle analyzer (AA）crystal are popular now; one uses a Bragg type AA that was first proposed by Chapman et al who gave a name diffraction-enhanced imaging (DEI) ; the second one using a Laue type AA (LAA) was proposed by Ingal et al and by Chapman et al. In the Laue optics the condition of LAA thickness to produce a condition of x-ray dark-field imaging (DFI) was given. If a certain thickness of LAA was chosen the intensity of forward diffraction (FD) becomes zero at the just Bragg angle if LAA receives plane wave.
In 2000-2006 three papers of DEI-based CT (DEI-CT) imaging were presented. Later the concept of refraction-based tomosynthesis for sliced images was presented. At long last algorithm for DFI-based CT (DFI-CT) was proposed.
As a result we can say that a technique to visualize soft tissue for clinical and pathological diagnosis such as breast cancer and articular cartilage ex vivo is now ready with DFI, so that a variety of breast cancers and articular cartilage are under imaging. Furthermore this technique will be potentially extendable to all other cancers. All details including a potential prospect for clinical and pathological use will be presented in the seminar.

12月11日—12日中午11：30—13：20，材料学院1208班将在综合楼门口（食堂门口）举办主题团日活动第二期——“最美”主题征集活动。
第二阶段活动以“美丽生活无处不在，发现生活最美瞬间”为主线，征集照片、短信、音乐评论三种作品类型。立意角度不限，只要你认为能表现出“最美”含义即可。
本期活动将设一等奖1名、二等奖3名、三等奖5名，我们将为获奖作品举办作品颁奖典礼，并对获奖作品提供者给予丰厚礼品。
欢迎学校全体师生参与！
