IBA Launches Compass Two-in-One Radiation Therapy Plan Verification System

Compass provides needed flexibility for optimal QA efficiency enabling measurement as well as full 3-D calculation-based independent treatment plan verification

August 9, 2013 — IBA (Ion Beam Applications S.A) has launched its Compass 3.0 plan verification system. Compass, the first patient anatomy-centric and solution for advanced intensity-modulated radiotherapy (IMRT) and rotational plan verification now provides a new two-in-one solution: calculation-based, full 3-D independent treatment plan system (TPS) verification and measurement-based quality assurance (QA) for the complete treatment chain, including linear accelerators.

Compass offers full workflow flexibility, allowing physicists and dosimetrists to choose the most efficient QA for any clinical need.

The new Compass also provides crucial calculation time saving and therefore much faster QA workflows. Dose calculations of 7 beam IMRT plans are done in just one minute, and more sophisticated 1 arc volumetric modulated arc therapy (VMAT) plans in just over two minutes.

With its powerful collapsed cone algorithm for independent dose calculations, Compass allows TPS-class dose calculations on real patient computed tomography (CT) as well as real patient CT-based DVH, and 3-D Gamma.

Independent beam modeling of individual linacs enables flexibility in precisely modeling as many machines as needed for highly accurate plan verifications. Physicists can measure and compare real linac delivery versus TPS-planned delivery as well as analyze the effect of segment errors on the total treatment accuracy. Plan verification is a step in radiation therapy to ensure treatment accuracy and patient dose safety.
