摘要
目的:研究控制扫描(CS)法精确确定放疗标记点CT层面的位置对头颈部肿瘤患者放疗的应用效果。方法:基于CS法制作标记点层面位置(MSP)计算程序,用于位置计算的企业微信程序,以及头颈部肿瘤患者(层厚3 mm)的CT定位扫描中。选取2020年10月至2022年3月南京医科大学附属南京医院收治的60例头颈部位肿瘤患者,将使用CS法行CT定位扫描的患者纳入观察组,使用常规方法行CT定位扫描的患者纳入对照组,每组30例。对两组CT定位扫描中3个金属标记点同时显示在同1层面的例数及含标记点CT图像的层数等进行对比分析。结果:观察组和对照组患者3个标记点同时显示在同1层面上的例数分别为26例和13例,观察组比对照组增加了13例(占43.4%),差异有统计学意义(χ^(2)=12.382,P<0.05);观察组和对照组含标记点CT图像仅1层的例数分别为4例和0例,观察组比对照组增加4例(占13.3%),差异有统计学意义(χ^(2)=2.411,P<0.05)。结论:使用CS法辅助头颈部肿瘤患者的放疗CT定位扫描,可精确计算得到CT定位扫描的目标起始位置,从而使放疗患者3个金属标记点的影像尽可能出现在同1个CT层面,具有较好的应用效果。能够有效提高放疗的便捷性和工作效率。
Objective:To study the position of computed tomography(CT)slice of marker points of radiotherapy,which was determined by control scan(CS)method,on the application effect of patients with head and neck tumors who received radiotherapy.Methods:Based on Control Scan(CS)method,a calculator program of mark-point slice position was made,which was an enterprise WeChat program that could be used in calculating position and CT position scan of patients with head and neck tumor(slice thickness was 3mm).A total of 60 patients with head and neck tumor were selected,and the patients who underwent CT positioning scan by using CS method were divided into observation group,and patients who underwent CT position scan by using conventional method were divided into control group,with 30 cases in each group.The number of cases with three metal marker points displayed at the same slice,and the number of slices containing the CT images of marker point between the located CT scan were compared.Results:The number of patients in the observation group and the control group who showed three markers at the same level at the same time were respectively 26 cases and 13 cases,and observation group increased by 13 cases(43.4%)than control group,and the difference was significant(χ^(2)=12.382,P<0.05).The number of CT images with only 1 slice of observation group and control group were respectively 4 cases and 0 cases,which increased by 4 cases(13.3%)than the control group,and the difference was significant(χ^(2)=2.411,P<0.05).Conclusions:The CT localization scan of radiotherapy,which uses CS to assist patients with head and neck tumor,can precisely calculate and obtain the primary position of target of CT localization scan.It can take the images of 3 mental marker points of patient who receives radiotherapy to occur at the same CT slice as soon as possible,which has better application effect.It can effectively improve the convenience and work effectiveness of radiotherapy.
