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-e ectiveness. 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 recon- struction algorithm and the representative applications of micro-CT are summarized. Some results from our research group are also pre- sented to show high-resolution images obtained by the micro-CT system.

Clipping is a simple and convenient PAPR （peak-to-average power ratio） reduction method for high speed OFDM （orthogonal frequency division multiplexing） communication system. In this paper, we propose a new PAPR reduction method for Wireless-MAN（metropolitan area network）-OFDM system based on IEEE 802.16, which is over-sampling clipping arithmetic. Simulation and performance of the over-samples clipping＇s PAPR reduction capability, BER effect is given. The simulation indicates that the PAPR of at least 99.9% OFDM symbol is below 6dB after 2 Nyquist rate clipping, and the performance of BER has 1dB SNR（signal noise ratio） loss. The results prove that this method has better capacity to reducing PAPR. So it can be well used in WMAN-OFDM system.

Left ventricular pseudoaneurysm （LVPA） is a rare clinical entity that could be life-threatening. It could be of congenital and acquired origin. Among the acquired LVPA, post-infarction LVPA constitutes most of the cases. LVPA always occurs after acute myocardial infarction （MI） and develops chronically. Reliable diagnosis and early surgical intervention are vital for the patients＇ recovery. Here we present 7 cases of LVPA in Anzhen Hospital between May 1993 to March 2007, focusing on the evaluation of diagnosis methods and treatment efficiency of LVPA.

Aortic dissection and aortic aneurysm are two of the most common catastrophic events involving the aorta. Thoracic endovascular aortic repair is now considered as a promising alternative to open surgical graft replacement. The aim of endovascular repair of a thoracic aneurysm is to exclude, and thus depressurize, the aneurismal wall and the aim of the endovascular repair of type B aortic dissection is to obliterate all of the false lumen through thrombosis after sealing the primary entry tears, thus to ensure the true lumen perfusion. But in some special pathologies, such as when the aneurysm and chronic type B dissection are aligned in tandem, or when a visceral branch originates from the false lumen, how should the endovascular repair strategy proceed in this situation？ For the endovascular stent repair of some special chronic type B aortic dissection, the false lumen cannot be obliterated, and the true and false lumens in the dissected but with a normal diameter distal aorta need to be perfused at the same time, as practiced in the surgery treatment. In this report, we present a case of endovascular stent repair for a special thoracic aneurysm and chronic type B aortic dissection aligned in tandem.
