Monte Carlo Comparison of Dose-to-Air-Kerma Ratios for Kilovoltage Ionization Chamber Dosimetry
Background: Comparative studies show that at kilovoltage energies, EGSnrc and Geant4 can differ by several percent in ionization chamber response, particularly in small air cavities and steep dose gradients. These discrepancies are primarily attributed to dif...

Toward Patient-Specific Monte Carlo Dosimetry of the Vektra Electronic Brachytherapy System: A Proof of Concept
This work demonstrated the feasibility of performing in-water dose calculations with Monte Carlo (MC) simulations of the Vektra Electronic Brachytherapy (EB) system (Empyrean, Boca Raton, FL). The Vektra is a novel method of EB, using beam steering and intern...
