Magnetic resonance imaging system comprising a power supply unit adapted for providing direct current electrical power

A MRI system for acquiring MRI image data comprising a data acquisition means comprising a plurality of subunits for acquiring MRI image data, a power distribution means for providing the means for acquiring MRI image data with electrical power, the power distribution means comprising:

• a power supply unit adapted for providing direct current electrical power from an alternating current electrical mains,
• a power bus adapted for supplying the subunits with the direct current electrical power,
• a control means for controlling the supply of direct current electrical power by the power bus to the subunits, and
• wherein one of the subunits is a radio frequency amplifier for powering radio frequency coils, wherein the radio frequency amplifier is adapted to be powered with a direct current electrical power.
