| 摘 要： | 目的探讨食管癌在影像引导下进行放射治疗(IGRT)时的六维最佳配准范围。方法20例食管癌病人,其中男性18例,女性2例;年龄27～68岁,平均年龄45岁。病灶部位食管胸上段2例,食管胸中段18例。在IGRT的摆位误差纠正前,行锥形束计算机X线断层摄影术(CBCT)图像扫描,并选取不同的配准范围与计划CT图像进行图像配准。以手动配准为基准,比较使用骨配准方式对4种配准范围:椎体、椎体+棘突、椎体+肺尖、椎体+棘突+肺尖等的配准结果的差异。结果用4种配准范围进行配准与手动配准比较,在平移方向上的Z轴平移中椎体配准最差,其余相似。平均差异的幅度以椎体+棘突+肺尖配准为最小。在旋转方向的X轴旋转中,椎体+棘突+肺尖配准有优势,其余各种方法均相似。差异的幅度从小到大为椎体+棘突椎体+棘突+肺尖椎体椎体+肺尖配准。结论食管癌骨配准时最佳的配准范围是椎体+棘突+肺尖。

| Abstract: | Objective To explore the 6-dimensional registration scope of esophageal cancer during image-guided radiotherapy (IGRT). Methods A total of 20 patients with esophageal cancer were enrolled,male 18 and female 2,aged 27-68 years,mean age 45 years. There were 2 cases in upper thoracic esophagus and 18 cases in middle thoracic esophagus. Cone beam computed tomography(CBCT) images were acquired before IGRT. The registration between CBCT images of 4 different kinds of registration scope and the planned CT images o... |
