摘　　要：目的分析在胸部肿瘤患者放疗摆位中应用锥形束CT图像引导的效果。方法选择2020年1月—2023年7月曹县人民医院收治的40例胸部肿瘤患者为研究对象,所有患者均接受常规电子射野影像仪图像检查与锥形束CT图像检查,分别作为对照组与研究组,比较两组不同方向摆位偏差、时间相关指标。结果研究组患者的不同方向摆位偏差均低于对照组低,差异有统计学意义(P均<0.05)。研究组的摆位时间为(150.52±14.29)s,长于对照组的(49.53±15.29)s,差异有统计学意义(t=30.519,P<0.05)。两组图像获取时间比较,差异无统计学意义(P>0.05)。结论在胸部肿瘤患者放疗摆位中实施锥形束CT图像检查可减少方向摆位偏差。Objective To analyze the effect of cone beam CT image guidance in radiotherapy of patients with chest tumors.Methods Forty patients with chest tumors admitted to Cao County People's Hospital between January 2020 and July 2023 were selected as the study objects.All patients underwent routine electronic field imaging and cone beam CT image examinations,and they were included in the control group and the study group,respectively.The positioning deviation in different directions and time related indicators were compared between the two groups.Results The positioning deviations in different directions of the study group patients were lower than those of the control group,and the differences were statistically significant(all P<0.05).The positioning time of the study group was(150.52±14.29)s,which was longer than(49.53±15.29)s of the control group,and the difference was statistically significant(t=30.519,P<0.05).There was no significant difference in image acquisition time between the two groups(P>0.05).Conclusion The application of cone beam CT image examination in the radiotherapy of thoracic tumor patients can reduce the orientation deviation.
