Stereotactic body radiation therapy (SBRT) is a high-precision radiation therapy technique that enables to deliver a high ablative biological dose in 1 to 5 high dose-fractions despite sparing the high dose of adjacent organs at risk. SBRT has emerged as an alternative to conventional radiation therapy for spinal metastases and has been applied to patients with non-spine bone metastases as well. Since bone SBRT is the technique of high biologically effective dose to the local lesion, quality assurance (QA) of the entire treatment process is an essential for performing SBRT. This report provides QA procedures for performing bone SBRT.
立体定向体部放射治疗（SBRT）是一种高精度放射治疗技术，能够在1至5次高剂量分割中给予高消融生物剂量，同时避免对高剂量的相邻危及器官造成损伤。SBRT已成为脊柱转移瘤传统放射治疗的替代方法，也已应用于非脊柱骨转移患者。由于骨SBRT是对局部病变给予高生物有效剂量的技术，整个治疗过程的质量保证（QA）对于实施SBRT至关重要。本报告提供了实施骨SBRT的QA程序。
