Dynamic 2.5D Surface Dosimetry Using Deformable Scintillator Array Imaging

Authors: Petr Bruza, Megan Clark, David J. Gladstone, Lesley A Jarvis, Allison Matous, Roman Vasyltsiv, Rongxiao Zhang

Affiliation: Dartmouth Health, Dartmouth College, Thayer School of Engineering, Dartmouth College, Dartmouth Cancer Center, University of Missouri

Abstract Preview: Purpose: On-patient dosimeters assist in clinical decision-making by measuring surface dose, but single-point measurements cannot monitor area-wide distributions and are misleading in high-gradient re...

Evaluation of the Hyperscint RP-200 Plastic Scintillation Dosimetry System for Reference Dosimetry in Ultra-High Dose Rate Electron Beam Therapy: A Comparative Study

Authors: Julie Colnot, Eric Deutsch, Christelle Huet, Danahé LeBlanc, Pauline Maury, Charlotte Robert, Imane Saïd Mansour, Cathyanne Schott, Francois Therriault-Proulx

Affiliation: INSERM U1030, Gustave Roussy, University Paris-Saclay, LDRI, IRSN, Medscint, THERYQ / INSERM U1030, Gustave Roussy, University Paris-Saclay, Université Paris-Saclay, Gustave Roussy, Inserm U1030, Radiothérapie Moléculaire et Innovation Thérapeutique

Abstract Preview: Purpose: FLASH radiotherapy, using ultra-high dose rates (UHDR, >100 Gy/s), spares healthy tissues while maintaining tumor control compared to conventional radiotherapy (CONV). However, UHDR dosimetry...

“You Can’t Unsee It”: Clinical Scintillation Imaging Enables First Localized Comparison between In Vivo dosimetry Measurements and the Treatment Plan

Authors: Petr Bruza, Megan Clark, David J. Gladstone, Lesley A Jarvis, Allison Matous

Affiliation: Thayer School of Engineering, Dartmouth College, Dartmouth Cancer Center, Dartmouth Health

Abstract Preview: Purpose: In vivo dosimetry (IVD) is underutilized, in part, because measured point doses cannot be accurately localized to the patient or treatment planning system (TPS), complicating the clinical and...
