Abstract

A breast coil for a magnetic resonance tomography device for the production of magnetic resonance recordings of female breasts includes a coil housing having a breast recess to accommodate a breast and a number of coil elements. At least one of the coil elements forms an HF correction coil element and has a circuit arrangement to switch over the HF correction coil element between an HF correction mode of operation and another mode of operation. The HF correction coil element is constructed such that in the HF correction mode of operation, the HF correction coil element resonates passively with a B 1 field emitted by a transmission antenna arrangement of the magnetic resonance tomography device, and influences a local B 1 field distribution during a magnetic resonance recording.

First claim

The invention claimed is:

1. A breast coil for a magnetic resonance tomography device for producing magnetic resonance recordings of female breasts, the breast coil comprising:
a coil housing comprising a breast recess to accommodate a breast;
a plurality of coil elements, wherein at least one coil element of the plurality of coil elements forms a high frequency (HF) correction coil element; and
a circuit arrangement operable to switch the HF correction coil element between an…
