Low operating costs Consumption of liquid helium for cryogenic cooling is minimized in booth measurement positions to reduce operating cost. Low boil-off rate provides a long refill interval of seven days. Low system noise - Low noise gradiometers: white noise typically 3 fT/(cm√Hz)
- Low noise magnetometers: white noise typically 3 fT/√Hz
Optimal sensor design - Field distribution sampled by 510 coils at distinct locations. Coils configured into 306 MEG channels
- The coil configuration optimally combines the focal sensitivity of 204 planar gradiometers and the widespread sensitivity of 102 magnetometers
- Accurate geometry and excellent balance of the sensors provided by thin-film technology
- Interference compensation by on-line Signal Space Projection (SSP) using the sensor array as a reference; involves no increase of white noise
- Whole-head design with realistic shape based on standard (EN960:1994)
High performance data Acquisition - Up to 450 channels can be sampled simultaneously. Distributed, upgradeable architecture based on multiple parallel real-time computers
- Digital signal processors to ensure precise and identical filtering and sampling of all channels
- Resolution of conversion: 24 bits/sample, samples are stored on disk as 16-bit words
- Sampling rate for 306 MEG and 64 EEG channels: 5 kHz as standard, 8 kHz as an option
- Fully integrated EEG system with 60 single ended and 4 differential channels. Additional 64 single-ended channels available as an option
- Two EEG-caps, adult and child sizes, other sizes available as options
- DC and AC measurement for both MEG and EEG
- 16 digital trigger lines, 8 auxiliary analog input channels
- 12 miscellaneous +/– 10 V analog output channels available as an option

- Mobile patient bed with adjustable upper bed
- Mobile patient chair. Rigid gantry minimizes vibration artefacts; head is supported by the helmet itself to gain minimal distance between functional brain areas and the sensors
- Optional pediatric chair-insert
Head Phantom - 32 current dipoles down to 34 mm from phantom origin and 4 magnetic dipoles
Workstation configuration - Acquisition workstation (HP Model C3700 or equivalent) and analysis workstation (HP Model B2600 or equivalent). Dual monitor configuration in both workstations
- 512 Mbyte of RAM, 36 Gbyte hard disk per workstation, and CD-ROM/DVD-ROM drive
- 9.1 Gbyte magneto-optical disk drive or equivalent. 20-40 Gbyte DDS4 DAT drive (compressing) or equivalent
- Optional high-reliability RAID-server with DLT backup system including CD-RW unit
Powerful software Elekta’s newest breakthrough for purified and standardized data is MaxFilter™. This software feature filters all magnetic interferences and artifacts, and provides your analysis with reliable data. Both internal disturbances, for example pacemakers and bracelets, and external, such as elevators, power lines are filtered. MaxFilter is based on Signal Space Separation method. Lifetime Commitment Elekta provides introductory as well as advanced MEG training courses developed by experienced teachers at leading institutions. Elekta offers advice and support so that the Elekta Neuromag® site can operate at peak efficiency. With our obsolescence programs, outdated computers, servers and peripherals can be proactively exchanged or upgraded. For more information on this product please complete our contact form. | |
