Acuros™ BV

Advanced Dose Calculation for Brachytherapy

Acuros BV is an enhancement of BrachyVision's dose-calculation abilities, bringing new levels of precision and accuracy to treatment planning in time frames previously thought unimaginable.

While the dose calculation for brachytherapy is generally calculated as if the sources are in water, Acuros BV accounts for the effects of

  • the applicator materials
  • patient tissues & boundaries
  • tissue air interfaces
     

Acuros BV provides Monte Carlo-accuracy dose calculations with speed and ease. Click a button to run the calculations, and you view the inhomogeneity-corrected dose for a plan. Calculations take approximately 1 minute typically** compared with the gold-standard Monte Carlo, which can take hours or days.

Acuros BV is a Grid-Based Boltzmann Solver (GBBS). GBBS codes directly solve the Linear Boltzmann Transport Equation. It deterministically solves what the Monte Carlo codes solve stochastically. Comparatively, Acuros BV provides the accuracy of Monte Carlo more quickly, without the wait or statistical noise.

Acuros can be used with versions of BrachyVision 8.9 and higher. Acuros BV calculations can only be performed on Varian HDR/PDR afterloaders. Acuros for Eclipse is Acuros XB.
