Abstract

The invention relates to a nuclear magnetic resonance imaging apparatus comprising: a main magnet (122) adapted for generating a main magnetic field; at least one radio frequency receiver coil unit (144) for acquiring magnetic resonance signals in a receiver coil radio frequency band (202) from an examined object (124); means (140) for inductively (wirelessly) supplying electric power to an electric component of the apparatus, wherein the electric component is adapted to be powered by inductively supplied electric power, wherein the power transfer frequency (200) and the higher-harmonics (206) of the power transfer frequency (200) for inductively supplying the electric power are located outside the receiver coil radio frequency band (202).
