Breast coil for magnetic resonance recordings of the breast
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 B1 field emitted by a transmission antenna arrangement of the magnetic resonance tomography device, and influences a local B1 field distribution during a magnetic resonance recording.
