英文摘要	High radiation dose impedes the development of in-vivo micro-CT. In this paper, we presents a low dose and fast in-vivo micro computed tomography (micro-CT) system based on equally sloped tomography (EST) technique and the monochromatic synchrotron X-ray source. Comparing with regular CT, the projection number required for our imaging system can be reduced by about 75%. In addition, combining with an X-ray shutter, total exposure time of 4 seconds and about 0.67Gy absorption dose for a set of CT data have been achieved. These results demonstrate that micro-CT with monochromatic synchrotron X-rays has great potential in the investigation into the microstructure evolution inside a small animal for biomedical research.
