id="article_content"><P>自从X光在1895年被发现后，医学界便广泛利用它作诊断用途。X光拥有能穿透物质的特性，相同的X光能量，对于不同密度的物质，有不同的穿透能力。因为人体的器官及骨骼有着不同的密度，当X光投射及穿透人体某个部位后，便能在菲林（X光片）上造成深浅不同的影像。这些影像对于病症诊断有很大的帮助，最常见的检查是应用于诊断骨折（fracture）及肺部的疾病上。近年，一些介入性（interventional）而有治疗作用的X光检查，也很普遍。根据统计，<a href="http://medicine.oecr.com" target="_blank" class="relatedlink">医疗</a>诊断仪器中， X光的使用便占了百分之六十。</P> <P>X光在医学发展历史中扮演了举足轻重的角色，从小诊所到大医院， X光造影通常是第一线的诊断工具， 当 X射线穿过物质时，会产生两种<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>现象； X光的吸收与折射。传统的 X光造影呈像，是利用射线穿过不同物质吸收时，在底片表现出的灰白色阶影像，通常影像的对比及分辨率较差。传统的 X光诊断，有其技术上与安全上尚未突破的盲点，特别是软组织病变的侦测，因此研究者从 X光的物理特性来试着改善目前医疗诊断所遇到的瓶颈。于是部分的研究学者开始探讨有关 X光折射在医学影像的应用，希望透过不同的成像方式，可以得到理想的诊断结果。</P> <P>在瑞士洛桑(Lausanne)Ecole Polytechnique Federale的 Giorgio Margaritondo教授和他的同僚，发展了一项根据 X射线折射为<a href="http://theory.oecr.com" target="_blank" class="relatedlink">理论</a>基础，对全身造影的新技术。他们认为这项科技，有机会取代计算机断层与核磁共振仪在现今医疗诊断的功能。折射现象发生在 X射线或其它的电磁波，例如光线等穿过不同介质，行径方向改变的一种物理现象，折射的角度取决于行径不同的两种介质组成。当 X射线穿过身体，经过不同的组织、器官后，会呈现多变化的折射现象，这复杂的折射纪录透过计算机的运算，可以计算出身体中目标物体的密度与位置，相较于传统的 X光诊断，这种利用折射原理所产生的相对比 (phase-contrast)技术，其优点在于得到更精确清晰的造影，并且可以快速的照像而形成电影般的纪录，甚至可以应用在个别细胞及基本结构的观察。</P> <P>临床上使用的 X光源为全方向的扩散，然而这项科技的缺点是因为所处理的信息中所包含的几何光束，需要在 X光起始的方向上作精准的连结，达到一致的相位。目前研究小组利用同步幅射仪的磁场中，高能<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电子</a>所产生连续的 X射线来进行研究，但同步辐射仪体积庞大，使用金额高，无法使用于例行性的临床研究上。</P> <P>传统的 X光诊断中，辐射是最令人担心的问题，尤其越精密的检查需要越高剂量的 X射线，但高剂量幅射容易导致癌症的发生与恶化，进而降低了民众检查的意愿。目前瑞士研究小组正利用相比对技术进行小动物、昆虫及鱼类的临床实验，而意大利的研究团队，希望能够将这项技术应用在乳癌的筛检。不仅是因为这项科技的准确性，能够克服传统 X光技术在软组织诊断上的不足，降低诊断潜在的危险，得到更准确的检查结果，未来甚至可以应用在更多疾病例如心血管病变的诊断上，让这些例行性的检查，更具有安全性与准确性。</P> <P><A href="http://www.oecr.com/batch.download.php?aid=117" target=_blank><IMG border=0
