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.

A base plate is engageable with a moveable support element connecting the shoulder coil posterior part to the base plate to permit lateral movement and 90 degree rotation of the shoulder coil posterior part. With the base plate beneath the patient, the shoulder coil posterior part is placed below the first shoulder and the shoulder coil anterior part is placed above the first shoulder to permit acquisition of magnetic resonance measurements. To acquire signals from the opposite second shoulder, the shoulder coil posterior part is moved across the base plate to be positioned beneath the second shoulder and is rotated by 90 degrees. The shoulder coil anterior part is placed above the rotated shoulder coil posterior part.
