目的 腹部皮下脂肪是影响宫颈癌放射治疗摆位的重要因素,影响着宫颈癌的放疗精度.本研究应用锥形束CT(cone beam CT,CBCT)探究腹部皮下脂肪厚度与体积对宫颈癌摆位误差的影响,对摆位工作和临床计划靶区体积(planning target volume,PTV)外扩范围提供建议.方法 选取2016-01-01-2019-02-01南华大学第一附属医院55例宫颈癌患者为研究对象,对患者摆位固定,进行CT定位.治疗前应用首次CBCT扫描获取的图像,再与CT定位图像自动配准并手动微调,计算患者分别在x轴(左右方向)、y轴(头脚方向)、z轴(腹背方向)3个方向的摆位误差,并用治疗计划系统测量腹部皮下脂肪厚度及体积,并对厚度和体积分别分为3组.结果 ...

OBJECTIVE: Abdominal subcutaneous fat is an important factor affecting the positioning of cervical cancer radiotherapy, affecting its radiotherapy accuracy. This syudy was to investigate the effect of abdominal subcutaneous fat thickness and volume on cervical cancer setup errors by cone beam computed tomography(CBCT), and provide advice on positioning work and clinical planning target volume(PTV) expansion. METHODS: The study was adopted to analyze 55 cervix cancer patients from the First Affiliated Hospital of University of South China, and t...
