Cs-131 tile implant–based intracranial brachytherapy requires coordinated interdisciplinary efforts spanning imaging, source management, implantation, post-implant planning, and radiation safety. The extent of inter-institutional variability in these practice...
To determine the optimal thickness of an electron skin collimator that minimizes the surface dose inhomogeneity (“hot” spots), which reached up to 23% for previous prototypes, while maintaining the prior penumbral advantages.
Efficacy, feasibility, and safety of extracranial, single-fraction MR-guided adaptive radiotherapy (SMART-1fx) was reported in the SMART ONE trial (NCT04939246). This work evaluates SMART plan quality relative to RTOG-0813 standards for an expanded cohort.
