摘要:
 目的：探讨CT能谱成像技术的质量检测方法。 方法：采用自行制作的碘试剂原型体模在西门子force双源CT和GE Discovery CT750 CT上，运用常用头部条件进行能量扫描实验，然后用双方的后处理工作站上进行图像定量分析。 结果：在临床常用的单能量模式下，得到两者在60、70、80 keV能谱图像，经过对比两者的CT值吻合，再通过能谱成像等功能软件如等效原子序数直方图、基质散点分布图和CT值随射线能量变化曲线图，实现对不同浓度的碘溶液进行区分和定量分析其碘基含量。 结论：经过利用原型体模分别对西门子force双源CT和GE 750能谱CT进行一系列的能谱扫描实验，证明该体模检测CT能谱成像技术的质量是可行的。
Abstract:
 Abstract: Objective To discuss the quality testing method for spectral computed tomography (CT) technology. Methods Based on the conditions for head scan, we used a self-produced iodine reagent phantom to carry out energy scanning experiments on SIEMENS force dual-source CT and GE Discovery CT750 CT. The obtained images were quantitatively analyzed by the post-processing workstation of the two CT systems. Results In the single-energy mode, the spectral CT images under the energy of 60, 70 and 80 keV were obtained, and the obtained images on the two CT systems had agreement CT values. The iodine radical content in iodine solution with different concentrations was distinguished and quantitatively analyzed with the spectral imaging software such as equivalent atomic number matrix histogram, matrix scatter diagram and CT value-energy curves. Conclusion The energy scanning experiments using self-produced iodine reagent phantom on SIEMENS force dual-source CT and GE Discovery CT750 CT verify that using the proposed self-produced iodine reagent phantom for the quality assurance of spectral CT technology is feasible.
