摘　　要：目的:分析Monaco与Pinnacle计划系统在感兴趣区体积计算上的差异,为临床应用提供参考。方法:在Pinnacle计划系统上,分别勾画1,5,10层的三角形、六角形和圆形ROI。同时选取头、胸、腹部肿瘤各10例,在Pinnacle计划系统上勾画常见的正常器官ROI。将图像和ROI从Pinnacle上通过DICOM协议传输至Monaco计划系统,分析两种计划系统计算的ROI体积。结果:两种计划系统对ROI的体积计算有差异,特别是小体积的ROI有明显的差异。结论:两种计划系统间传输ROI时,特别是小体积的ROI,应当注意ROI体积计算的差异。Objective： To analyze the differences region of interest volume between Monaco and Pinnacle planning system, and provide reference for clinical application.Methods：Delineate 1,5 and 10 slices triangles, hexagonal and circular contours in Pinnacle treatment planning system.Meanwhile select 10 cases with head neck tumor, lO cases with chest tumor and 10 cases with abdomen tumors.Transfer image and ROI to Monaco treatment plan system by DICOM protocol.Compare ROI volume between two kinds of TPS.Results：There are significant differences in the volume of ROI between the two kinds of TPS, especially for small volume ROI. Conclusions：When the transmission ROI between two kinds of planning systems, especially the small volume ROI, should pay attention to the difference of ROI volume calculation.
