In this paper, the effects of the rigid body motions and low frequency surface errors on the image quality were analyzed. Quadratic equations were used to build the mathematical model of the Wolter type I and II X-ray telescopes and reduce the computational complexity of ray tracing. With the help of a self-developed optical surface analysis code, the effects of the perturbations of the mirrors on the image quality was analyzed and the growth of the image spot formed by deformed telescopes was calculated, this is important for giving the reasonable fabrication tolerance.

BMSCs were isolated, depurated, cultivanted, and identified,then incubated with the concentration of 25μg Fe per milliliter at 37℃in 5% CO2. The labeled cells were stained by Prussian blue/trypan blue,and observed under fluorescent microscope.2. The labeled cells of different density (1×104/ml,5×104/ml,1×105/ml,5×105/ml,1×106 /ml,5×106/ml)were imaged by MRI with T1WI, T2WI and T2*WI sequences;and the same density (5×104/ml,1×105/ml)labeled cells were imaged by T2*WI sequences at different time.Then the signal intensities were measured and statistically analyzed.3. The model of rabbit renal ischemia-reperfusion injury was set up and treated. Then BMSCs(5×105)were injected into 16 recipient rabbits(1abeled cells in 10,unlabeled cells in 6)from ear vein.MR images of kidneys were obtained respectively at the time points of 0,1,3,5, 8 days after transplantation and before transplantation. MR imaging findings were analyzed,which were correlated with histological findings.
