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
