Avoiding numbers of high field drawbacks, very low field MRI requires sensitive detection devices .We have developed a novel magnetic sensor based on a combination of spin electronics and superconductors, labelled mixed sensor, and reaching sensitivities in the fT range at low frequencies down to 1kHz. This mixed sensor was inserted in a small scale prototype system and in vivo images were successfully acquired at 7mT, showing high performance and versatility of the sensor for very low field MRI.
