July 10, 2019 — IBA announced the launch of the latest functionality of the SciMoCa Monte Carlo Patient QA solution at the 61st annual American Association of Physicists in Medicine (AAPM) annual meeting, July 14-18 in San Antonio, Texas. The new release of SciMoCa provides what IBA calls 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 stereotactic body radiation therapy (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 (quality assurance) 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 (linac) 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 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.
The SciMoCa software is manufactured by Radialogica LLC and globally distributed by IBA Dosimetry.
