Abstract: The success of the high resolution in X-CT scanners have been reviewed, it has major application in small animal imaging. The industrial computed tomography (ICT) with micro-focus has reached spatial resolution 5~20um,which have been applied to examine the tissues and cells of tats and obtained the distinct microscopic CT images. Micro CT images of the pyramidal neurons of the cerebral cortex, the Bowman's capsule of the glomerulus of kidney and the structure of the hepatic lobules were first reported, Results were very exciting It means that the advanced technologies of ICT can be available to improve the spatial resolution of the medical CT and that the micro CT may be used in making beauty.
