We have built the first full-scale brain scanner performing both MRI and neuromagnetic measurements. Many improvements have been made compared to previous-generation systems. Parts of the system include a helmet-shaped array of 120 superconducting sensors and a pulsed superconducting polarizing coil. An open-geometry coil system provides unobstructed access, and MRI signal acquisition is performed at ultra-low field. The first MEG and MRI data have been successfully obtained with the device. The new prototype is an important milestone on the way towards a commercial implementation.
