Study on X-ray Coherent Scatter Imaging Using Clinical X-ray Imaging Equipments

进行在临床影像设备条件下X射线相干散射成像的研究。通过改进影像设备的准直、聚焦设备,实现更加清晰的成像。经过后期的图像处理,获得确定的光子能量空间分布的图像和曲线,进一步深化了实验研究结果。通过对影像设备的改造,获得了更具有实验说服力的实验图像,经过对实验图像的算法分析,可以肯定临床CR影像设备上进行成像是可行的,面向临床应用的X射线相干散射成像将是进一步的研究目标。在普通X射线影像设备上的X射线相干散射成像研究,是这种成像方式向应用发展的关键步骤。通过对实验设备的优化和改造,达到了预期的成像精度。

To validate the X-ray coherent scatter imaging with the clinical X-ray imaging equipments. An experimental fiat was built with the clinical X-ray imaging equipments. On this flat the imaging for a series of samples was made clearlier. The images and curves for the analysis of energy distribution were obtained by image processing methods. The images obtained in different conditions have special traits. After image processing, the result showed the energy distribution was fixed. By improving the imaging equipment, more persuasible clinical imges were obtained. Analysis for the algorithm of experimental images proved the imaging with clinical X-ray equipment is valid. So the imaging with clinical equips is a key way to make the coherent scatter imaging used in clinical way. The experimental result validated the theory, of coherent scatter and supported the advanced experiment.
