This study aimed to evaluate and compare different system calibration methods from a large cohort of systems to establish a commissioning procedure for surface‐guided frameless cranial stereotactic radiosurgery (SRS) with intrafractional motion monitoring and gating. Using optical surface imaging (OSI) to guide non‐coplanar SRS treatments, the determination of OSI couch‐angle dependency, baseline drift, and gated‐delivered‐dose equivalency are essential.

颅面无框立体定向放射外科光学表面成像系统的调试

这项研究旨在评估和比较来自一大批系统的不同系统校准方法,以建立具有面内运动监测和门控功能的表面引导无框架颅骨立体定向放射外科手术(SRS)的调试程序。使用光学表面成像(OSI)指导非共面SRS治疗,确定OSI卧床角度依赖性,基线漂移和门控输送剂量当量是必不可少的。
