February 7, 2008 - The first image-guided intensity modulated arc therapy patient treatment using commercially released product solutions was completed using Elekta Synergy image guided system fitted with the new Elekta linear accelerator control system.
The Royal Marsden Hospital in Sutton UK used an Elekta Synergy image guided system fitted with the new Elekta linear accelerator control system in order to deliver volumetric intensity modulated arc therapy (VMAT) to a patient undergoing a course of radiation therapy treatment for lung cancer.
Allgemeines KrankenHaus/Medical University of Vienna (AKH) in Austria delivered the world’s first PreciseBEAM VMAT treatment. PreciseBEAM VMAT is delivered as a combination of optimized treatment planning using Ergo and an Elekta Synergy linear accelerator, upgraded with a next generation digital control system.
The treatment was to an intracranial glioblastoma and consisted of 3 noncoplanar VMAT arcs with variable gantry speed and simultaneous leaf movement and rotation of the dynamic multileaf collimator. The patient had a brain lesion very close to vital structures such as hypophisys, brain stem, optical nerves, and lenses of the eyes, however the treatment was completed within 10 minutes – including set-up, Imaging, repositioning and delivery.
VMAT capability is CE marked as part of the new linear accelerator control system and may require additional regulatory clearances for sale in other regions of the world.
