Advanced Physics for Brachytherapy 2018

Dosimetry using Dosimetry using a Grid-Based Boltzmann equation Solver (Acuros) • GBBS algorithms used primarily for neutron transport and shielding problems • Method evaluated for brachy in the literature as early as 2000 • The first GBBS algorithm incorporated in a commercially available 192 Ir brachytherapy TPS was Acuros • Acuros is based on the Attila GBBS developed at Los Alamos National Laboratory, optimized for brachytherapy and later also for external beam therapy (XB) and even CT scatter correction (CTS).

Method can be reviewed in a number of publications: ✓ Daskalov GM et al 2000 Med. Phys. 27(10):2307 ✓ Daskalov GM et al, 2002 Med. Phys. 29(2): 113 ✓ Gifford K A et al, 2006 Phys. Med. Biol., 51(9): 2253 ✓ Gifford et al 2008 Med. Phys. 35(6): 2279 + ✓ BV-Acuros user manual
