A magnet suitable for use in a Magnetic Resonance Imaging (MRI) system. The magnet includes a magnet body having a bore extending therethrough along an axis of the body and a primary coil structure having at least four primary coils positioned along the axis. A first end coil is adjacent a first end of the bore of the magnet and a second end coil is adjacent a second end of the magnet. The first end coil and the second end coil are spaced apart by no more than 1000 mm and an imaging region produced by the primary coils is of a disk-type.

Magnets and magnetic resonance imaging systems

A coil arrangement for use in a magnetic resonance imaging system, the imaging system being for generating a magnetic imaging field in an imaging region, the coil arrangement including at least three coils for at least one of transmitting, receiving or transceiving an electromagnetic field, each coil being provided on a coil geometry and being substantially orthogonal.

Coil arrangement for use in a magnetic resonance imaging system

A coil for a magnetic resonance imaging device consists of multiple coil elements arranged about an imaging space. Each coil element comprise radiating structures oriented at an angle to a tangent of the imaging space. Angling the radiating structures reduces mutual coupling between coil elements and enhances the penetration of the radio frequency field to the imaging space.

MRI coil design with volumetric trough-shaped coil elements

Apparatus for use in a magnetic resonance imaging system, the imaging system generating a magnetic imaging field in an imaging region (), the apparatus including at least one coil for at least one of transmitting, receiving or transceiving an electromagnetic field, a field component () (such as a coil or a shield) and a drive () coupled to the field component for moving the field component () relative to the imaging region () to thereby modify the electromagnetic field during imaging process. The same concept can also be applied to nuclear imaging or nuclear spectroscopy apparatus.

MRI apparatus and method with moving field component

A Magnetic Resonance Imaging (MRI) phased array head coil () comprises an array of coils () a decoupling circuit () and a decoupling base (). Counter wound inductors from adjoining coils () in the decoupling circuit () are interlaced to achieve mutual decoupling between adjoining coils. Each separate coil () includes a pair of spaced parallel main conductors () located on opposite sides of a cylindrical space () enclosed by the coils (). The decoupling base () comprises two meandering conductor bases () which are interlaced. Orthogonal main conductors () of the coil () share a common conductor base (). The multiple crossings of the paths of the conductor bases () reduces mutual coupling effects.
