Elekta Neuromag® is an advanced magnetoencephalography (MEG) device providing real-time mapping of brain activity by non-invasively measuring the magnetic fields produced by the brain. An Elekta Neuromag® examination answers questions like: - What activity is the brain producing and where does it originate from?
- Which parts of the brain undertake various tasks?
- How does the brain function, both normally and in cases of illness?
Elekta Neuromag® is technically one of the most sophisticated MEG/EEG devices available on the market today. The unique design of the sensors combined with advanced software makes it possible to gain data with unsurpassed detail even from the deepest realms of the brain. The system also has the highest available immunity to magnetic interference, either patient related or external. Elekta Neuromag® also has the lowest operational costs, with the longest liquid helium refill interval. What is MEG used for?- Simultaneous measurement of 306 magnetoencephalography (MEG) and 64 electroencephalography (EEG) channels - localizing functional areas most accurately
- Flexible and highly developed software - helps to perform time efficient data analysis.
- Ultra-low system noise - resulting in reliable diagnosis
- Fully supine and seated positions - easy to change, giving optimal patient comfort
- Low cryogen consumption - providing reduced operation costs
MEG technology is used both in research and for clinical purposes. Pre-surgical mapping for neurosurgery, MEG-MRI integration to enhance accuracy of surgical navigation and planning of radiation therapy are some common areas where MEG is used. Research programs could for example be psychiatric disorders; such as schizophrenia and depression; learning disorders, such as dyslexia as well as normal cognitive functions, underlying memory and language. An increasing area for MEG is also mapping of epilepsy. For patients with drug resistant focal epilepsy, surgery is an increasingly common alternative and MEG is proving useful for locating epileptogenic zones in relation to other functionally important cortical regions. | | How does it work?A brain signal is extremely small (femto Tesla range). Electrical activity in neurons produces magnetic fields that can be recorded outside the skull and used to identify the locations of the activity within the brain. The magnetic signals passes unaffected through brain tissue and the skull, so it can be recorded outside the head. To record the signals a superconducting quantum device (SQUID) immersed in liquid helium is used. This eliminates the impedance and allows for high sensitivity. To successfully obtain clinical MEG a magnetic shielded room is needed to eliminate magnetic noise generated in the environment. Powerful softwareThe data is transferred to the Elekta Neuromag® advanced software. The software provides extensive capabilities for data acquisition and processing, source modeling and anatomic visualization as well as DICOM 3.0-based image transfer system with full compatibility with other systems. The software is intuitive, straight-forward and easy to use. Unique sensor designThe detector array of Elekta Neuromag® system comprises triple-sensor elements that are evenly distributed over the entire head. The size and extend of the detector array ensure that activities from even the most peripheral areas, such as frontal and temporal lobes and the cerebellum can be acquired with high precision. 
The sensor elements consists of two orthogonal planar gradiometers and one magnetometer coupled to a multi SQUID (Super QUantum Interference Device) The patient helmet array provides field distribution sampling 510 distinct positions, with sensors configured a total of 306 independent channels.
