Innovative solution for Adaptive radiotherapy

Addressing the issues of legacy systems

1st generation systems are plagued by design shortcomings

• Perpendicular magnetic field to the beam impacts treatment quality
• High power MRI in connection with perpendicular field generate ERE and ESE
• Closed circular MR creates claustrophobia and tunnel effect
• Bores of small diameter increase patient unease
• No tangential treatment (no couch lateral move)
• High temperature MR require liquid helium and quenching

• Innovative open bi-planar superconductive MR
• Room temperature MR, no liquid helium and no quenching
• Robust 6 MV Linac
• 120 leaf high performance MLC
• Largest bore 110 W 60 H
• Rotating Linac with the 360 gantry, beam eye imaging
• Real time adaptive planning
• TPS agnostic, no dedicated MRI TPS
• Beam modulation, VMAT and IMRT
• Standard bunker, through the maze installation
• Unique high throughput, 15-30 patients per day
• Gating and tracking available at launch

• No ERE, no ESE
• Optimum Contrast to Noise ratio
• Large Patient Opening 110 x 60 cm Bore
• Dedicated non obstructive coils
• Ability to make lateral shifts to treat tangentially
• Open magnet minimizes claustrophobia
• No helium gas, no quenching, no refill
• Easy turn off for servicing

The Aurora RT™ can move patients’ side to side (laterally) allowing the treatment of peripheral tumors resulting in less damage to healthy tissue and a more accurate treatment.

The ability to laterally adjust a patient is crucial to treat all types of cancer in an efficient manner, broadening the clinical scope of Aurora RT

Significant improved precision will allow additional clinical indications that are conventionally treated with radiation while reducing the side effects.
