The high-resolution micro-computed tomography (micro-CT) system has now become an important tool for biological research. The micro-CT system enables a non-invasive inspection to screen anatomical changes in small animals. The promising advantages include high-spatial resolution, high sensitivity to bone and lung, short scan time and cost-effectiveness. The dose received by the small animal might be a critical concern in the research. In this article, the choice of the components, fundamental physical problems, the image reconstruction algorithm and the representative applications of micro-CT are summarized. Some results from our research group are also presented to show high-resolution images obtained bv the micro-CT svstem. 相似文献

人的眼睛可以看到6.1km远,鹰的视力却超出人的视力8~9倍。它的眼睛在高空时是远视眼,在低飞时是近视眼。鹰翱翔于3km高空中,能从许许多多景物中,准确地发现和辨认地面上的田鼠、黄鼠等小动物,甚至水里的鱼类,它不断调节视距和焦点,变远视为近视,准确无误地掠过地面,把猎物抓住…… 相似文献
