Dosimetric evaluation of Acuros XB Advanced Dose Calculation algorithm in heterogeneous media

Dosimetric evaluation of Acuros XB Advanced Dose Calculation algorithm in heterogeneous media

BACKGROUND A study was realised to evaluate and determine relative figures of merit of a new algorithm for photon dose calculation when applied to inhomogeneous media. METHODS The new Acuros XB algorithm implemented in the Varian Eclipse treatment planning system was compared against a Monte Carlo method (VMC++), and the Analytical Anisotropic Algorithm (AAA). The study was carried out in vir...

VARIAN MEDICAL SYSTEMS CLINICAL PERSPECTIVES ACUROS XB Acuros® XB advanced dose calculation for the EclipseTM treatment planning system

Clinical implementation and evaluation of the Acuros dose calculation algorithm

PURPOSE The main aim of this study is to validate the Acuros XB dose calculation algorithm for a Varian Clinac iX linac in our clinics, and subsequently compare it with the wildely used AAA algorithm. METHODS AND MATERIALS The source models for both Acuros XB and AAA were configured by importing the same measured beam data into Eclipse treatment planning system. Both algorithms were validated...

Accuracy of the Small Field Dosimetry Using the Acuros XB Dose Calculation Algorithm within and beyond Heterogeneous Media for 6 MV Photon Beams

Purpose: The dosimetric accuracy of the recently released Acuros XB advanced dose calculation algorithm (Varian Medical Systems, Palo Alto, CA) is investigated for single radiation fields incident on homogeneous and heterogeneous geometries, as well as for two arc (VMAT) cases and compared against the analytical anisotropic algorithm (AAA), the collapsed cone convolution superposition algorithm...

On the dosimetric impact of inhomogeneity management in the Acuros XB algorithm for breast treatment

BACKGROUND A new algorithm for photon dose calculation, Acuros XB, has been recently introduced in the Eclipse, Varian treatment planning system, allowing, similarly to the classic Monte Carlo methods, for accurate modelling of dose deposition in media. Aim of the present study was the assessment of its behaviour in clinical cases. METHODS Datasets from ten breast patients scanned under diffe...
