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
  • Bore of small diameter increases patient discomfort
  • No tangential treatment (no couch lateral move)
  • High temperature MR requires liquid helium and quenching
  • Very low throughput of 6-10 patients per day makes financials challenging
  • Innovative open, bi-planar superconductive MR
  • Robust 6 MV Linac
  • 120 leaf high performance double focus MLC
  • Largest bore in the market 110 W 60 H
  • Rotating Linac with 360 gantry, beam eye imaging
  • Real time adaptive planning
  • TPS agnostic, no dedicated MRI TPS
  • Beam modulation, VMAT and IGRT/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
  • Dedicated non obstructive coils
  • Ability to make lateral shifts to treat. tangentially, 23 cms left and right
  • Open magnet minimizes claustrophobia
  • Room temperature MR, no liquid helium and no quenching, no regular costly refill
  • Easy turn off for servicing
