Elekta, which develops tools and treatment planning systems for radiation therapy and radiosurgery, as well as workflow enhancing software systems across the spectrum of cancer care, and The Paul Scherrer Institute (PSI) in Switzerland are collaborating to further develop treatment planning and oncology information systems (OIS) for proton therapy.

Elekta recently received 510(k) clearance from the US Food and Drug Administration for XiO to plan spot scanning, a proton therapy delivery method that involves constructing a conformal placement of dose to the tumor by using thousands of small individual beamlets instead of a single large beam.

PSI integrated Elekta’s XiO treatment planning system and MOSAIQ OIS into its Centre for Proton Therapy to manage the flow of information and image data between treatment delivery, treatment planning, treatment simulation and the patient’s electronic medical record.

PSI Center for Proton Therapy Medical Physics head Antony Lomax said through XiO, Elekta provides a combination of advanced tools for scanned proton beam therapy and also provides a clear road map to further develop intensity modulated, image guided and adaptive proton therapy.

"MOSAIQ is designed to support different types of radiation systems and modalities, including proton and carbon ion therapy, Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT) and Volumetric Modulated Arc Therapy (VMAT) all in alignment with Elekta’s long-standing history of supporting multiple vendors and open systems to support new technologies," Lomax said.

Elekta Particle Therapy director Stewart Pegrum said their collaboration with PSI focuses on combining technological advances in conventional radiation therapy and proton therapy to create the best possible therapeutic solution.
