摘要

X射线相位衬度CT能获得样品内部结构的边缘增强图像

可观察到传统X射线吸收CT无法观察到的生物软组织内部微细结构

具有巨大发展潜力。经初步调试

上海光源X射线成像实验站的8-72.5keV单色X射线输出已能用于实验研究。本文在X射线成像实验站上开展生物样品（蝗虫）同轴X射线相位衬度CT研究

获得蝗虫样品的切片重构图像和三维重建图像。结果图像中

蝗虫样品的翅膀、表面纹理和内部组织分布情况清晰可见。

Abstract

With X-ray phase contrast micro-tomography(CT)

one is able to obtain edge-enhanced image of internal structure of the samples.This allows visualization of the fine internal features for biology tissues

which is not able to resolve by conventional absorption CT.After preliminary modulation

monochromatic X-rays(8-72.5 keV) are available for experiments on the experimental station of the biomedical imaging beamline at Shanghai Synchrotron Radiation Facility(SSRF).In this paper

we report the in line phase contrast micro-tomography(IL-XPCT) of biology sample(locust) on the beamline.The reconstruct slice images and three dimensional rendering images of the locust were obtained

with clearly visible images of locus’s wing

surface texture and internal tissue distribution.
