We evaluate the performance of a 4-channel plastic scintillator for real-time dose monitoring during VMAT total body irradiations (TBI).

Metals in computed tomography (CT) scans often saturate image pixel values, making low- and high-density metals indistinguishable. The purpose of this work was to test the effectiveness of the extended HU mode on a GE Discovery RT16 CT scanner to distinguish...

Gold nanoparticles (GNPs) are promising radiosensitizing agents for high dose rate brachytherapy (HDR); however, complex treatment delivery for HDR has prohibited systematic evaluation of GNP-induced radiosensitization both in vitro and in vivo. Here, we use...

Interrupted patient treatments that are split into multiple partially delivered trajectory log files for a given field may be most susceptible to Linac delivery errors. The AAPM TG-100 recommends independent QA checks to prevent the most hazardous failure mod...
