| Research Abstract |
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.
