This work reports on the results obtained for VIC-T dosimeter for radiotherapy dosimetry (17 % (w/v) N-vinylpyrrolidone, 8 % (w/v) N,N′-methylenebisacrylamide, 12 % (w/v) tert-butyl alcohol, 5 % (w/v) gelatine, 0.02 % (w/v) hydroquinone and 14 mM tetrakis (hydroxymethyl) phosphonium chloride (THPC)) measured with a spiral computed tomography (CT). Optimal spiral CT protocol, CT measurements conditions and image processing are provided. Basic features of VIC-T are discussed such as a calibration relation and dose resolution with respect to former N-vinylpyrrolidone containing dosimeters. Both adopted data processing performed with a new polyGeVero®-CT software package and its features are reported.

本工作报告了用于放射治疗剂量测定的 VIC-T 剂量计的结果（17 % (w/v) N-乙烯基吡咯烷酮，8 % (w/v) N,N'-亚甲基双丙烯酰胺，12 % (w/v) 叔-丁醇、5 % (w/v) 明胶、0.02 % (w/v) 氢醌和 14 mM 四（羟甲基）氯化鏻 (THPC)）通过螺旋计算机断层扫描 (CT) 测量。提供最佳螺旋CT协议、CT测量条件和图像处理。讨论了 VIC-T 的基本特征，例如与以前含有N-乙烯基吡咯烷酮的剂量计有关的校准关系和剂量分辨率。两者都采用了使用新的 polyGeVero®-CT 软件包进行的数据处理及其功能。
