硬X射线衍射增强峰位成像CT的几何失真纠正方法

A Calibration Method for the Misaligned Geometry of Hard X-ray Diffraction Enhanced Top Position Imaging CT

    摘要
  • 摘要: 近年来X射线相位衬度成像技术作为一种新的成像方式凭借其空间分辨率高的优势已经成为生物、医学以及材料科学等领域一种新的独具本领的研究工具。本文针对平行束情况下应用相位衬度成像技术得到的放置在胶囊内的苍蝇及蜜蜂投影图片进行重建,对系统几何失真进行了分析和纠正,很好地提高了重建图像的质量,验证了利用目标自身的信息进行自动校正的可行性。

     

    Abstract: Recently the technique of phase contrast imaging has become an useful and special tool in biology, material science etc. due to its high resolution. In this paper, we reconstruct the fly in a capsule, calibrate the misaligned geometry by sample information itself. The quality of the CT images is greatly improved and the efficiency of the calibration method is proved.
