The invention provides a hospital bed driving device for a magnetic
resonance system. The magnetic
resonance comprises a
magnet of which the front has an upright post part, and the
hospital bed driving device comprises a bracket, side arms and a
hospital bed, the bracket comprises bottom edges and two side edges, and can be movably arranged on the upright post part of the
magnet and drive the bracket to move up and down through a motor; the side arms can be movably arranged on two sides of the bracket and are driven to move left and right through a motor; and the hospital
bed is arranged in the side arms and is driven by a motor to move left and right. Through the up-and-down, front-and-back and left-and-right movements of the bracket, the side arms and the hospital
bed, the three-dimension drive of the
bed is realized. At the same time, the motors driving the bracket, the side arms and the hospital bed are all arranged on the rear surface of the magnetic and do not move with the hospital bed, thereby avoiding influence on the shimming parameters of the
magnet and on the
imaging quality of the image of magnetic
resonance equipment.
