Information display device and control device of medical equipment

A control device of magnetic resonance equipment, the control device comprising:

• an information display device of the magnetic resonance equipment, the information display device comprising:
• a projector configured to acquire display information and project the display information onto a surface of a housing of the magnetic resonance equipment, the housing defining a bore hole of the magnetic resonance equipment;
• a host operable to provide an electrical signal of the display information;
• an optical fiber converter operable to convert the electrical signal into an optical signal;
• and
• an optical fiber operable to relay the optical signal to the projection unit;
• a light capture device configured to capture light change information about a display image projected onto the housing of the magnetic resonance equipment;
• a position encoder operable to determine a control instruction based on the light change information, wherein the position encoder comprises an optical position encoder;
• a controller configured to control the magnetic resonance equipment based on the control instruction;
• and
• a photoelectric converter arranged between the position encoder and the controller, the photoelectric converter configured to convert a light control instruction determined by the optical position encoder to an electrical control instruction,
• wherein the controller is configured to control the magnetic resonance equipment based on the electrical control instruction.
