Varian Redesigns ProBeam Proton Therapy User Interface

New Interface Showcased at PTCOG 51 Meeting in Seoul, Korea

May 15, 2012 — Varian Medical Systems is showcasing a new user interface for its ProBeam proton therapy system at the annual meeting of the Particle Therapy Co-Operative Group (PTCOG 51) taking place May 14-19 in Seoul, Korea. The new interface streamlines the steps for imaging, positioning and treating patients with image-guided intensity-modulated proton therapy (IMPT).

The new user interface for the ProBeam system is based on technology that was developed for the TrueBeam system for radiotherapy and radiosurgery. This includes an easy-to-use treatment console that consolidates all controls for imaging, treatment and motion management in one graphical, easy-to-use interface.

"We have capitalized on Varian's long experience designing interfaces for efficient clinical use," said Moataz Karmalawy, head of Varian's particle therapy group. "Clinicians who are already conversant with the TrueBeam system should have an easy time learning to operate a ProBeam system, and moving back and forth between the two."

IMPT involves shaping the dose so that it matches the shape of the targeted tumor in three dimensions. Varian's ProBeam system utilizes Dynamic Peak scanning, which optimizes the dose applied to every point within the area being treated. This makes it especially useful for targeting tumors with complex shapes, or tumors that wrap around critical structures like the spinal cord. Another feature of the system, Dynamic Peak imaging, enables the use of imaging to further enhance the accuracy of tumor targeting.

"Varian's ProBeam system has been developed as a complete solution that is tightly integrated with the ARIA oncology information system and Eclipse treatment planning," said Karmalawy. "This enables an efficient and integrated workflow for planning and delivering high-quality image-guided IMPT treatments."
