In X-ray astronomy, the great contribution was made by discovery of the principle of the SUDARE collimator in our country in the world. We developed various imaging technology, in order to develop this technology in medicine.The analyzer crystal was used for the 1^<st>. The resolution of angle measurement of X ray observation was improved to 0.25 seconds. The accuracy of 3-dimensional measurement of X-rays was also improved with this measurement technology, and the possibility of medicine application was opened. The principle of computed tomography which used refraction and diffraction phenomena using this method is developed, (refraction computed tomography) refraction computed tomography - density - resolution is connected with the medical diagnostic imaging equipment with which it is improved 1000 times and image quality differs from conventional X-ray absorption computed tomography furthermore. I improve spatial resolution, the 1-micrometer X ray point light source which used synchrotron radiation was developed. Development of the analysis algorithm of a new principle for refraction computed tomography was also performed. It is the algorithm of the refraction computed tomography analysis fundamentally required with polyhedron approximation. Moreover, it experimented by creating collimator of the shape of metaled Sudare.

在X射线天文学中，我国的SUDARE准直器原理的发现在世界上做出了巨大的贡献。为了在医学上发展这项技术，我们开发了各种成像技术，分析晶体被用于1^lt；st&gt；；X射线观测测角分辨率提高到0.25秒。该测量技术也提高了X射线三维测量的精度，为医学应用开辟了可能。发展了利用折射和绕射现象的计算机层析成像原理，将折射计算机层析成像-密度-分辨率与医学诊断成像设备连接起来，使其成像质量提高了1000倍，而且图像质量也不同于传统的X射线吸收成像。为了提高空间分辨率，研制了采用同步辐射的1微米X射线点光源。还开发了一种新的折射CT原理的分析算法。这是折射CT分析的算法，基本需要多面体近似。此外，它还通过制作金属苏达尔形状的准直器进行了实验。
