12. A method of operating a magnetic resonance imaging system, wherein the method is configured to operate a magnetic resonance imaging system, wherein the magnetic resonance imaging system is configured for acquiring magnetic resonance imaging data from an imaging zone, wherein the magnetic resonance imaging system comprises a main magnet configured for generating a B0 magnetic field within the imaging zone, wherein the magnetic resonance imaging system further comprises a subject support configured for moving a subject between a loading position and an imaging position, wherein the magnetic resonance imaging system further comprises a receive magnetic resonance imaging coil configured for being placed on the subject, wherein the magnetic resonance imaging system further comprises a light detection system comprising multiple ambient light sensors, wherein the light detection system is configured to measure spatially coded light data from ambient illumination, wherein the ambient illumination is spatially encoded in that it has a physical aspect that is different between the loading and imaging positions, wherein the light detection system is mounted to the receive magnetic resonance imaging coil and wherein the multiple ambient light sensors are configured for measuring ambient light distributed across a surface of the receive magnetic resonance imaging coil, wherein the method comprises:
moving the subject support from the loading position to the imaging position;
acquiring the spatially coded light data using the multiple ambient light sensors when the subject support is in the imaging position;
determining if the receive magnetic resonance imaging coil is positioned for acquiring the magnetic resonance imaging data using the spatially coded light data; and
providing a signal if the receive magnetic resonance imaging coil is positioned for acquiring the magnetic resonance imaging data.
