[Quality Assurance of Bone SBRT].

Abstract

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.
