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~ 20μm , which have been applied to examine the tissues and cells of rats 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. The making beauty treatment want knowledge of the relevant anatomy, physiology, and pathology. At this time, the three-dimensional reconstruction can display skin change and relationship with adjacent structure, which is very useful for clinical assistance examination and more favorable and more accurate for establishing surgical operation planning. The indication of using the three-dimensional spiral multi-slice CT reconstruction technique in making beauty with these management is discussed and some cases of clinic are demonstrated. We suggested that the medical micro CT should composed of the following properties and speculations: a small diameter focus spot (1~10μm ) of X- ray source, virtual collimation, hyper thin tomo-section (5~50μmm thick), super computer with vast storage volume, rapid imaging technique of the region of interest (ROI), image zooming technique,μCT and 3D stereological operation technique, etc. The micro CT will give a great impact on the clinical medicine and ＂Making beauty imaging＂　in the 21 century.
