1972年英国首台X-射线CT扫描设备问世，应用于临床医学。其基本原理在于利用物体内部物质的密度差，揭示物体内部的组成物质的分布。其最大的优点在于其非破坏性，但限定性因素使分辨能力有限，空间分辨率0.35×0.35mm2，可识别最小体积为0.12mm3，密度对比分辨率0.3%?中国科学院寒区旱区环境与工程研究所...

X-ray computed tomography systems for human use (30) for imaging the internal structure comprises a radiation source (22), which along a path to a generally conical X-ray beam is projected onto the object to be detected, such that at least the beam The portion to be detected by the ...
1.A new approach to the fastX-ray computed tomography(XCT) technique was proposed for the transient measurement of multiphase flow where the local phase concentration can be simplified to have binary values such as in a gas bubbling system.针对局部浓度场具有二值分布特征的特定多相流体系,提出引入...
X-ray检测 X 射线源 探测器 中游—X射线检测设备 下游—应用领域 工业 医疗 参考资料 基本概念 X射线(又称伦琴射线、X-Ray)是 1895年德国物理学家伦琴在研究阴极射线时发现的一种射线,系高速运动的电子在与物质相互作用中产生的。在X射线管中,从阴极发射的电子,经阴极、阳极间的电场加速后,轰击X射线阳极靶,...
X-ray micro-computed tomography (micro-CT) can provide detailed information regarding the position of the elastomer stopper and aluminum band both before and after the sealing process of parenteral vials. This information can be used to evaluate the closure integrity and identify if changes need to...
