Scintillation Imaging as Versatile Tool for Validation of UHDR Treatment Plans Across Modalities

Scintillation imaging has been shown to provide high spatio-temporal surface dose information for delivery verification of ultra-high dose rate (UHDR) beams. To obtain higher dose rates, modified clinical machines are often utilized, requiring extensive re-characterization and treatment validation. The goal of this work was to demonstrate the utility of 1.) projecting surface images to depth and 2.) quinine-doped water tank imaging for 3D beam verification across different UHDR treatment modalities.
