nanoScan MRI 7T
State-of-the-art MRI system with cryogen-free MRI, translational 7T MR field strength
The unique design of the patented superconducting “dry magnet” technology is inherently compact, low weight, with a negligible magnetic fringe field, and does not require liquid helium.
Key benefits for cryogen-free 7T MRI
- High performance at 7 Tesla: Performance is highlighted by excellent resolution and homogeneity covering routine and advanced imaging applications. The nanoScan MR 7T is an efficient and fast scanner providing whole body MR images within a few minutes.
- Homogeneity: Best-in-class “dry magnet” homogeneity of 1st and 2nd order auto shimming.
- High performance gradients: Powerful gradients (up to 600mT/m).
- Comprehensive coil selection: Animal specific, dedicated whole body and brain coils provide easy setup and an optimized signal-to-noise profile. A selection of surface coils give flexibility to closely cover anatomical regions. A phased array coil is available for more demanding imaging.
- Sequence library: Over 30 routine and advanced sequences and protocols are included with the flexibility of an optional pulse programming package.
- Advanced MR design at 7 Tesla: The cryogen-free, vacuum sealed superconducting magnet can be placed anywhere in a research facility, no dedicated or shielded rooms, and no interference with research equipment operating nearby. The Mediso design principles are based on providing a user-friendly, cost-effective, dependable, and high performing preclinical MR.
- Persistent mode operation: User-defined customizable field strength from 0.1T to 7T.
- Pulse tube cryocoolers: Pulse tube cryocoolers mitigate vibrations for artifact free imaging and ensure a long maintenance free lifetime.
- SMART magnet technology: Easily put the magnet in standby or hibernation mode and consume 1/3 the power compared to active imaging.
- Safety and monitoring:The nanoScan dry magnet technology does not suffer from magnetic field quenches often associated with traditional magnets.
- Mediso's SMART® magnet technology offers unrivalled Protection and Control by
- Active quench protection
- Monitoring environmental parameters
- Emergency self ramp-down
- Prolonging magnet / cold-head lifetime
- Ensuring optimal working conditions by multiple temperature, pressure and flow sensors
- Enabling Magnet operation in idle-mode
- Programming system operation
- Ensuring low consumption when the system is not in use
