Accurate real-time motion tracking is crucial for effective stereotactic body radiotherapy (SBRT) in lung cancer patients, particularly those with significant tumor motion. Techniques to reduce tumor motion, such as abdominal compression, breath hold, or respiratory gating, are often uncomfortable or result in longer treatment times. The Radixact Synchrony system (Accuray Inc., Sunnyvale, California, United States) enables continuous adaptation to tumor motion without the need for implanted fiducials. We report the case of a patient with a small target in the right lower lobe (RLL) with large tumor motion managed using Radixact Synchrony, highlighting treatment planning, delivery accuracy, and clinical outcomes.
精确的实时运动跟踪对于肺癌患者的有效立体定向体部放疗（SBRT）至关重要，尤其是对于那些肿瘤运动显著的患者。减少肿瘤运动的技术，如腹部压迫、屏气或呼吸门控，往往会让患者感到不适或导致治疗时间延长。Radixact同步系统（美国加利福尼亚州桑尼维尔市的Accuray公司）能够持续适应肿瘤运动，无需植入基准标记物。我们报告了一例右下叶（RLL）有小靶区且肿瘤运动较大的患者，使用Radixact同步系统进行治疗的病例，重点介绍了治疗计划、放疗准确性和临床结果。
