MRI compatible patient trolley

A trolley system configured to deliver air within an MRI room, the trolley system comprising:

• a base portion configured for movement relative to a floor;
• and
• an electric blower coupled to the base portion of the trolley system and fixed to prevent movement of the electric blower relative to the trolley system, the electric blower being configured to deliver air, and an elevation of the electric blower does not change when the blower delivers air, the electric blower being mounted such that the electric blower remains within a weaker portion of a magnetic field generated by an MRI apparatus in the MRI room, thereby reducing the effect of the magnetic field on the operation of the electric blower during use of the electric blower;
• and
• a battery for powering the electric blower;
• wherein the electric blower is configured to deliver air to a patient transfer device to facilitate movement of the patient transfer device relative to a patient support;
• wherein the trolley system is MR Compatible with a maximum magnetic attraction force less than or equal to 50 lbs force;
• and
• wherein the trolley system is positionable adjacent the MRI apparatus within the MRI environment and the magnetic field of the MRI apparatus does not interfere with the operation of the electric blower when the trolley system is positioned adjacent the MRI apparatus, such that the electric blower operates while adjacent the MRI apparatus and while the magnetic field is generated by the MRI apparatus.
