Camera-based patient monitoring in mri

A method for adapting a magnetic resonance imaging system, the method comprises:

• obtaining a magnetic resonance imaging system having an examination zone for positioning therein a subject to be imaged by the magnetic resonance imaging system, in which the magnetic resonance imaging system comprises an infrared camera system, which includes an infrared camera, for monitoring the subject while undergoing examination, and
• applying a coating on at least one wall of a room that houses the magnetic resonance imaging system, on an interior wall of a magnet assembly of the system, or on auxiliary equipment of the magnetic resonance system for use inside the examination zone, wherein said coating is adapted to at least one of absorb or diffusely reflect infrared light so as to avoid spurious reflections of infrared light into a field of view of the infrared camera and/or to provide diffuse auxiliary lighting,
• wherein said infrared camera is adapted to operate in an infrared wavelength range that corresponds to, or substantially overlaps with, the range over which said coating absorbs and/or diffusely reflects infrared light.
