Create a flat, vector-style illustration based on a photograph of a magnetoencephalography (MEG) scan. The illustration should include the following elements: a human head in profile, the MEG helmet with sensors clearly visible, and the magnetic field lines around the head. Use simple, clean lines and a minimal color palette, focusing on shades of blue, grey, and white. Label key parts such as the sensors, magnetic field lines, and the brain regions. Ensure the illustration is clear, professional, and suitable for inclusion in a scientific publication based on this image <https://s.mj.run/yVSqWPJzbC4>
