Monte Carlo Patient QA Accuracy for Varian Halcyon launch at AAPM by IBA Dosimetry

July 11, 2019

New SciMoCa™ Monte Carlo patient QA now enables fast and efficient Quality Assurance accuracy for the Varian Halcyon™ in addition to all other major radiation therapy systems.

San Antonio, TX, USA, July 10th, 2019 – IBA (Ion Beam Applications S.A.), the world’s leading provider of proton therapy (PT) solutions and radiation therapy integrated quality assurance (QA), announces the launch of the latest functionality of the SciMoCa Monte Carlo Patient QA solution at the 61st annual AAPM meeting. The new release of SciMoCa provides the first and only worldwide commercial Monte Carlo Patient QA for the Varian Halcyon™ System. Healthcare professionals can now verify all Halcyon treatment plans independently, accurately, and with an automated and efficient workflow. The fast Monte Carlo dose calculation enables highly accurate results even for the most challenging cases like non-coplanar SBRT, and in particular for indications with tissue inhomogeneity like lung and head & neck treatments.

Monte Carlo is the gold standard for dose calculation accuracy in treatment planning. With SciMoCa, the accuracy of Monte Carlo is now available for independent secondary dose calculation and patient QA as well, allowing users to verify the most advanced treatment plans with an equally robust and fast QA solution. SciMoCa is used clinically for all standard Linear Accelerator types, for the Accuray® CyberKnife® and TomoTherapy®/Radixact, and is now also compatible with Varian Halcyon.

The high-quality beam models for SciMoCa are created linac-specific for customers applying dedicated processes, expert tools and experience. This unique process allows an independent verification of the commissioning data and the TPS model, providing an additional level of peace of mind about the accuracy of the machine and TPS commissioning. This is particularly valuable for pre-commissioned treatment machines like Halcyon.

“We are proud to introduce the first and only Monte Carlo patient QA solution for the Varian Halcyon™ at the AAPM 2019. This advancement to SciMoCa will enable customers to significantly save QA time whilst increasing the quality of patient treatment,” said Jean-Marc Bothy, President of IBA Dosimetry GmbH. “With SciMoCa’s workflow automation, calculation speed, and proven accuracy, we offer a real game changer in advanced 3D patient QA for the Halcyon™ and for all other major treatment systems.”

The SciMoCa software is manufactured by Radialogica LLC and globally distributed by IBA Dosimetry. To find out more please visit
