摘要
显微CT(Micro-computed tomography,Micro-CT)是一种新型的采用X射线成像原理进行超高分辨率三维成像的设备。可以在不破坏样品的情况下,对各种材质样品或活体小动物进行高分辨三维成像。本文介绍了一种高分辨显微CT系统开发,通过小昆虫样品的投影与断层图像,清晰显示了边缘增强的相位衬度效应。同时,断层图像显示了系统的细节分辨能力高于12微米。
Micro-CT is a new three dimensional imaging tool based on x-ray imaging mechanism and with ultrahigh spatial resolution. It can be used to image all kinds of samples or live small animalsunder non-destructive condition. In this paper, a micro-CT prototype system with high spatial resolution was developed. From the projective images and reconstructed cross-sectional images of a small insect sample, the phase-contrast effect with the edge-enhancement trait can be observed clearly. The cross-sectional images also show that the developed micro-CT system has the detail detectability down to 12 micrometers.
