Neurospin MRI research. Researcher preparing a test subject for scanning in an advanced magnetic resonace imaging (MRI) machine. This is the 3T MRI scanner at Neurospin, one of the most advanced MRI research centres in the world. The 3T designation refers to the magnetic field strength of 3 Tesla. This is an extremely strong magnetic field, and hence this technique is known as ultra high-field magnetic resonance imaging. The high magnetic field strength allows detailed examination of the brain and brain disorders. Neurospin also has a 7T scanner, and there are plans for an 11.7T scanner. Neurospin was founded in 2006, and is located near Paris, France. Photographed in 2007.
