Apparatus for imaging during surgical procedures includes an operating room for the surgical procedure and an MRI for obtaining images periodically through the surgical procedure by moving the magnetup to a table. A magnet wire is formed of a superconducting material, such as magnesium di-boride or Niobium-Titanium, etc., which is cooled by a vacuum cryocooling system to superconductivity withoutuse of liquid helium. The magnet weighs less than 1 to 2 tonne and has a floor area in the range 15 to 35 sq feet, so that it can be carried on the floor by a support system having an air cushion covering the base area of the magnet having side skirts so as to spread the weight over the entire base area. The magnet remains in the room during surgery and is powered off to turn off the magnetic field when at the second position remote from the table. 用于外科手术中的成像的设备，包括用于外科手术的手术室和用于通过将磁体向上移动到手术台而在外科手术过程中周期性地获取图像的MRI。磁线由超导材料形成，例如二硼化镁或铌钛，该超导材料通过真空低温冷却系统冷却至超导，而无需使用液氦。磁体的重量小于1至2吨，占地面积为15至35平方英尺，因此可以通过支撑系统将其放在地板上，该支撑系统具有气垫，其覆盖了
