Abstract
Gradient coils for generating gradient magnetic fields in a magnetic resonance imaging system are provided. In one embodiment, a gradient coil for a magnetic resonance imaging system may include a plurality of turns formed generally in a figure-eight. The figure-eight may form a first section configured to overly a section of a first adjacent coil, a second section configured to underly another section of the first adjacent coil, a third section configured to overly a section of a second adjacent coil, and a fourth section configured to underly another section of the second adjacent coil.
Claims20
A gradient coil for a magnetic resonance imaging system comprising:
- a plurality of turns positioned such that the gradient coil is generally shaped as a figure-eight.
A gradient coil for a magnetic resonance imaging system comprising:
- four coils, each coil having a plurality of turns formed generally in a figure-eight;
- wherein the coils are interleaved in a generally cylindrical configuration with a first section of each coil overlying a corresponding underlying section of a preceding coil and a second section underlying a corresponding overlying section of the preceding coil.
A gradient coil for a magnetic resonance imaging system comprising:
- first and second X coils disposed at diametrically opposite locations in a generally cylindrical configuration;
- first and second Y coils disposed at diametrically opposite locations in the generally cylindrical configuration and displaced at 90 degrees with respect to the X coils;
- wherein the coils are interleaved with an overlying section of each X coil overlying a corresponding underlying section of each adjacent Y coil and an underlying section of each X coil underlying a corresponding overlying section of each adjacent Y coil.
