Two liquid systems have been developed for the measurement of effective photon energy (Eeff) and "linearity" in computerized tomography (CT). A group of sixteen "keV liquids" enables an Eeff to be rapidly determined, by comparing the CT numbers of the specially formulated organic liquid mixtures with similar data for water. The "linearity" of the CT scanner, relating CT nubers to linear attenuation coefficients, may be investigated using 14 selected organic "linearity liquids". Details of these systems, together with some typical results, are presented.
已经开发出两种用于测量计算机断层扫描（CT）中有效光子能量（Eeff）和“线性度”的液体系统。一组十六种“keV液体”通过将特殊配制的有机液体混合物的CT值与水的类似数据进行比较，能够快速确定Eeff。可以使用14种选定的有机“线性度液体”来研究CT扫描仪的“线性度”，即CT值与线性衰减系数的关系。本文介绍了这些系统的详细信息以及一些典型结果。
