| Outline of Final Research Achievements |
In this study, we aimed to develop a new method for imaging the X-ray emission site without using a lens system by using a MURA code mask with Bi deposited on the Kapton film. Since the adhesiveness between the Kapton film and Bi was insufficient, fine patterns fell off at etching Bi. This maks it impossible to produce a mask for practical use. The software for reconstructing the image was evaluated using simulated data, and we were able to wrote a software that can be reconstructed correctly. Furthermore, the performance of the software has been improved, and it has become possible to process at a practical speed.
It was clarified that the imaging of the X-ray emission site without using a lens system is sufficiently practical, although it is insufficient at present.

| Academic Significance and Societal Importance of the Research Achievements |
X線によるイメージングの研究ではX線を透過させることによって生じる吸収・回折・屈折を用いるものがほとんどであり，中にはnmオーダーの分解能を持つイメージング方法が開発されている．一方，蛍光・散乱によって試料から発生するX線を用いるイメージング方法はほとんど研究が進んでいない．本研究はこの分野に新たなイメージング方法を提供するものであり，観察装置の進化により新たな研究テーマ・研究方法を生み出すきっかけとなりうるものである．
