Imaging method for surgical procedure

A device for imaging during a surgical procedure includes an operating room for a surgical procedure; and an MRI for periodically obtaining images during surgery by moving a magnet onto a table. A magnetic wire is formed of a superconducting material such as magnesium diboride that is cooled to superconducting by a vacuum cryogenic cooling system without the use of liquid helium. The weight of themagnet is less than 1 ton, and its footprint is between 15 and 25 square feet, so it can be carried on the floor by a support system having an air cushion covering the bottom region of the magnet with side skirts, thereby dispersing the weight throughout the bottom region. The magnet remains in the operating room during surgery, and the magnet is arranged to be de-energized to close the magneticfield when the magnet is in a second position away from the table. 一种用于在外科手术过程中成像的装置，包括用于外科手术的一手术室；和一MRI，用于通过将磁体移动到台上，在手术过程中周期性地获得图像。磁线由诸如二硼化镁的超导材料形成，二硼化镁通过真空低温降温系统冷却至超导而不使用液氦。磁体重量小于1吨，且其占地面积在15到25平方英尺之间，因此它可以通过一支撑系统承载在地板上，该支撑
