COIL ARRAY POSITIONING

摘要

The invention is based, in part, on the recognition that patterns of coil elements can be arranged no surfaces with non-zero Gaussian curvature in an array having a reduced mutual inductance among the coils. For example, a coil array can include coil elements positioned according to the faces of a portion of a polyhedron. The coil elements can form a surface that is curved in two dimensions. The sizes of the coil elements are selected to reduce mutual inductance among the coils. Such coil arrays can be used to improve sensitivity in MRI systems significantly.
