Embodiment Construction

[0163] In the embodiment of the drawings, the device for surgical operation includes an operating room 10 having a floor 11 and a plurality of walls 12, and includes an operating table 13 for receiving patients for surgical operations. The workbench includes a work surface 14 on which the patient lies and an upright support 15, which is usually adjustable to move the patient to a desired position. The construction of a suitable workbench is well known in the prior art.

[0164] The operation table cooperates with the magnetic resonance imaging system 16 to obtain a part of the patient's image in multiple times during the entire surgical operation. After part of the operation is completed, these images are taken for the surgical team to evaluate the progress through analysis, so that the surgical team can monitor the progress of the operation.

[0165] The magnetic resonance imaging system 16 includes a magnet system 17 that includes a magnetic wire cylindrical magnet 18 that defin...

Abstract

An 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 magnet up to the table. The magnet wire is formed of a superconducting material such as magnesium di-boride or Niobium-Titanium 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 square 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 in the second position remote from the table.

Description

Technical field [0001] The present invention relates to a movable MRI system for surgery. Background technique [0002] Magnetic resonance imaging (MRI) is a non-invasive imaging mode that can distinguish various types of objects based on the inherent components of the object. At the same time, magnetic resonance imaging (MRI) is also a kind of one-dimensional, two-dimensional or three-dimensional imaging of objects. Imaging technology. A traditional MRI system usually includes a main magnet that provides a main static magnetic field, B0, a magnetic field gradient coil, and a radio frequency (RF) coil, which are used for spatial encoding, excitation and detection of atomic nuclei, to achieve imaging. Generally, the main magnet is designed to provide a uniform magnetic field in the inner area within the main magnet, for example, in the air space of the large central hole of the solenoid or in the air gap between the pole plates of the C-shaped magnet. The patient or object to be...
