Transportable intraoperative magnetic resonance imaging apparatus
First Claim
1. A transportable magnetic resonance imaging apparatus comprising:
- a transportable platform;
a magnetic resonance imaging system mounted onto said transportable platform, said magnetic resonance imaging system including a magnetic structure having a pair of spaced apart magnets bounding an imaging volume of sufficient shape and size to accommodate a patient'"'"'s body part for imaging;
a host computer mounted on the transportable platform and coupled to the magnetic structure so as to process and display a magnetic resonance image;
a magnetic flux suppressor provided on the transportable platform; and
a positioning assembly configured to move the magnetic structure between a first position in which the pair of spaced apart magnets are positioned within the magnetic flux suppressor so as to suppress the magnetic flux of the pair of spaced apart magnets, and a second position in which the pair of spaced apart magnets are deployed in an arrangement suitable for magnetic resonance imaging.

Abstract
A transportable magnetic resonance imaging apparatus, said apparatus comprising a transportable platform, provided with a casing made of ferromagnetic metal, and a magnetic resonance imaging system mounted onto said transportable platform, said magnetic resonance imaging system comprising a front end and a back end, the front end comprising a magnetic structure for the provision of a magnetic field, at least two gradient coils, RF transmit coil, and RF receive coil, and the back end comprising a host computer as a central processing unit, at least two gradient amplifiers, RF amplifier, MRI spectrometer, MRI controller and display unit, wherein said apparatus is provided with a positioning assembly for moving and positioning said magnetic structure between a first position and a second position, said first position being such that a patient'"'"'s body part is positioned between said magnetic field, and said second position being such that said pair of magnets is positioned inside said casing, when not in use, in order to suppress the magnetic flux of said pair of magnets outside said casing.
