Abstract
A brain measurement apparatus includes: a magnetoencephalograph including optically pumped magnetometers, magnetic sensors for measuring geomagnetic field at positions of the optically pumped magnetometers, magnetic sensors for measuring a fluctuating magnetic field at the positions of the optically pumped magnetometers, nulling coils for cancelling the geomagnetic field, and an active shield coil for cancelling the fluctuating magnetic field; an MRI apparatus including nulling coils for applying a static magnetic field and a gradient magnetic field, a transmission coil, and a receive coil; and a control device that, when measuring a brain's magnetic field, controls currents supplied to the nulling coils and the active shield coil based on measured values of the magnetic sensors and, when measuring an MR image, controls the static magnetic field and the gradient magnetic field by controlling currents supplied to the nulling coils and generates an MR image from an output of the receive coil.
