Local coil with a number of separately switchable local coil shim coils

摘要

A local coil for an imaging system includes a number of shim coils. A current for generating a shim field in one of the shim coils may be switched on and switched off. A current for generating a shim field in another of the shim coils may be switched on and switched off. The currents may be switched on and switched off independently of one another for generating a respective shim field in the shim coils.

1. A local coil for an imaging system, the local coil comprising:
one or more coil elements; and a plurality of shim coils, wherein a current for generating a shim field in one shim coil of the plurality of shim coils is switchable on and switchable off, wherein a current for generating a shim field in another shim coil of the plurality of shim coils is switchable on and switchable off, wherein the currents for generating the shim fields are switchable on and switchable off independently of one another in the one shim coil and the other shim coil, and wherein at least the one shim coil of the plurality of shim coils is located in the local coil at a position anterior, posterior, or anterior and posterior to a position for a head, a neck, or the head and the neck in the local coil, the one or more shim coils enclose the position for the head, the neck, or the head and the neck of a patient, or a combination thereof.
