项目摘要

The most atractive characteristics of synchrotron rediation X-ray for applying to medical use is, first of all, a extraordinary lot of photon number. This powerful photon density contributes to all of our researches in medical application. The second favorate characteristics is non-divergent beam, almost in parallel. This fact is utilized in a microdetection of metals in humantissue, fluorescent X-ray computed tomography and X-ray microscope.For two years where our group study was supported by the Grant-in-Aid for Co-operative Research(A), it made clear that there were two main problems to be solved. The first one is that the photon number at the beam line where we are now using is too small for the medical use. The second problem is that the experimental setup and its dismantlement every time we obtain machine time is time consuming and useless.In order to make our research in practical use we decided that a beam line for medical use with enough photon number must be constructed. Application of the proposal of Grant-in-Aid for Scientific Research on Priority Area has been concluded. Last February we applied the proposal to the Ministry of Education, Science and Culture.

同步辐射X射线在医学应用中最吸引人的特点首先是光子数的极大值。这种强大的光子密度有助于我们在医学应用中的所有研究。第二个特点是光束不发散，几乎平行。这一事实被用于人体组织中金属的显微检测、荧光X射线计算机断层扫描和X射线显微镜。在我们的小组研究得到合作研究补助金（A）支持的两年里，很明显有两个主要问题需要解决。第一个是我们现在使用的光束线上的光子数太小，不适合医学用途。第二个问题是每次获得机器时间所需的实验装置和调试都是费时而无用的，为了使我们的研究能够实际应用，我们决定必须建造一条具有足够光子数的医用光束线。优先领域科学研究补助金提案的申请已经结束。去年二月，我们向教育、科学和文化部申请了该提案。
