Background and purpose (extract): Intrafraction motion degrades the efficacy of radiation therapy. We reported on the implementation of focal dose-escalated stereotactic body radiation therapy (HypoFocal-SBRT) for prostate carcinoma on standard linear accelerator, and assessed whether periodic intrafraction image guidance (PIF-IG) improved the accuracy of treatment. Materials and methods (extract): Twenty prostate cancer patients underwent HypoFocal-SBRT. Patients […]
