A National Multi-Institutional Survey of Comprehensive Workflow and Quality Assurance In Cs-131 Tile Implants for Intracranial Tumors
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...

Benchmarking Heterogeneity-Aware 131Cs Intracranial Brachytherapy Using Monte Carlo Simulation and Patient-Specific Voxelized Lattice
Brachytherapy dose calculations are commonly based on the AAPM TG-43 formalism, which assumes a homogeneous water medium. Although widely used for HDR and LDR brachytherapy, this assumption inadequately represents dose distributions in heterogeneous tissues,...

Fractional Variability of High-Risk Clinical Target Volume and Organs-at-Risk during HDR Brachytherapy for Cervical Cancer
High-dose-rate (HDR) tandem and ring cervical brachytherapy requires significant time and resources from implant, to imaging, planning, and treatment. The high-risk clinical target volume (HR-CTV) and organs at risk (OARs) are contoured on MRI. To save time a...

Proof-of-Concept for Intraoperative Dosimetry Assessment of Gammatile Placement Using Intraoperative MRI and 3D Slicer Software
GammaTile cesium-131 collagen tiles provide immediate postoperative radiation therapy for brain tumors by lining the resection cavity, delivering a steep dose fall-off to target residual disease while sparing healthy tissue. However, intraoperative verificati...
