Abstract
A radio frequency antenna for conducting magnetic resonance imaging studies of the breast region of a patient includes a tuned primary coil inductively coupled to two tuned secondary coils. Each secondary coil defines a region for receiving one of the breasts of the patient, and receives magnetic resonance signals emitted from each breast and the surrounding region of the patient. The primary coil can be connected to the receiving circuitry of the magnetic resonance imaging system. The magnetic resonance signals received by the secondary coils induce signals in the primary coil which are provided to the magnetic resonance imaging system for processing. The secondary coils, which preferably include two windings, each have a portion adjacent to the primary coil and a portion distanced from the primary coil. The portions of the secondary coils adjacent to the primary coils preferably lie in substantially the same plane as the primary coil, while the portion of the secondary coil distanced from the primary coil lies in a second plane intersecting the plane of the primary coil. A cushion arrangement for supporting an antenna, and a method for collecting magnetic resonance signals from the breast region of a patient, are also disclosed.
