Embodiment Construction

[0079] The apparatus for surgery in the embodiment of the drawings comprises an operating room 10 having a floor 11 and walls 12 and containing an operating table 13 for receiving a patient for surgery. The table includes a table top 14 on which the patient lies and an upright support 15 which is generally adjustable to move the patient into a desired position. Suitable stage configurations are well known in the art.

[0080] The operating table cooperates with the magnetic resonance imaging system 16 to obtain images of a part of the patient in multiple times during the entire surgical operation. After part of the surgery, these images are taken for analysis by the surgical team to assess progress, allowing the surgical team to monitor the progress of the surgery.

[0081] The magnetic resonance imaging system 16 includes a magnet system 17 that includes a cylindrical magnet 18 of magnetic wire that defines a cylindrical bore 19 within which a portion of a patient is located...

Abstract

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.

Description

technical field [0001] The invention relates to an imaging method for surgery. Background technique [0002] Magnetic Resonance Imaging (MRI) is a non-invasive imaging modality capable of distinguishing various types of objects based on the inherent composition of objects, while Magnetic Resonance Imaging (MRI) is also a method that can provide one-dimensional, two-dimensional or three-dimensional imaging of objects. imaging technology. A conventional MRI system usually includes a main magnet providing a main static magnetic field, B0, magnetic field gradient coils and radio frequency (RF) coils for spatially encoding, exciting and detecting nuclei for imaging. Typically, the main magnet is designed to provide a uniform magnetic field in an inner region within the main magnet, for example, in the air space of the large center hole of a solenoid or in the air gap between the pole plates of a C-shaped magnet. A patient or object to be imaged is placed in a homogeneous field ...
