Abstract
In a method for determining the position of at least one local antenna in an examination chamber of a magnetic resonance apparatus, magnetic resonance signals emitted by a body arranged in the examination chamber are received, locus-encoded in at least one coordinate direction, by an antenna that has a homogeneous sensitivity distribution. From the received magnetic resonance signals, image data that are locus-resolved in the at least one coordinate direction are produced in the form of first intensity values. Magnetic resonance signals emitted by the body are received, locus-encoded in the coordinate direction, by the at least one local antenna. From the received magnetic resonance signals, image data that are locus-resolved in the at least one coordinate direction are produced in the form of second intensity values. From the second intensity values, normalized intensity values are formed by relating the second intensity values respectively to the first intensity values belonging to the same coordinate values. The normalized intensity values are searched for their largest value. A coordinate value that belongs to the largest normalized intensity value indicates the position of the at least one local antenna in the coordinate direction.
