Movable medical bed system and MRI apparatus

A magnetic resonance imaging (MRI) apparatus, comprising:

• a movable medical bed system including:
• a bed body including a bed frame, a bottom of the bed frame being spaced above a ground surface in a first direction;
• a power supply apparatus, including:
• an electrical energy receiver disposed at the bottom of the bed frame;
• an electrical energy transmitter disposed on or below the ground surface and configured to be connected to a power source, the bed body being moveable to a working position relative to the electrical energy transmitter in a second direction perpendicular to the first direction, wherein, in response to the bed body being located at the working position, the electrical energy receiver being spaced from the electrical energy transmitter in the first direction and configured to engage in electrical energy transmission, in the first direction, with the electrical energy transmitter without plugging-in;
• a first shielding cover arranged on the bed frame and being configured to shield an electromagnetic field;
• a second shielding cover configured to shield an electromagnetic field,
• wherein, in response to the bed body being located at the working position, the first shielding cover and the second shielding cover are arranged opposite one another in the first direction, and the first shielding cover is configured to move away from the bottom of the bed frame towards the second shielding cover to reduce a distance between the first shielding cover and the second shield cover in the first direction and collectively define a shielding space, the electrical energy receiver and the electrical energy transmitter being located in the shielding space;
• a wireless communication receiver arranged on the bed body, the wireless communication receiver being configured to receive a drive control signal by wireless telecommunication or optical wireless communication;
• a drive controller arranged on the bed body and connected to the wireless communication receiver to receive the drive control signal, the drive controller being configured to acquire electrical energy via the electrical energy receiver;
• and
• an electric motor arranged on the bed body and connected to the drive controller, the drive controller being configured to control the electric motor based on the drive control signal;
• a control system configured to generate a drive control signal;
• and
• a wireless communication transmitter connected to the control system, the control system being configured to send the drive control signal to the wireless communication receiver via the wireless communication transmitter by wireless telecommunication or optical wireless communication.
