Abstract:
A method for determining a position of a local antenna in an examination space of a magnetic resonance system, comprising the steps of:(a) receiving a magnetic resonance signal emitted by a subject in an examination space of a magnetic resonance system with a local antenna having a sensitivity profile, said magnetic resonance signal being location-encoded in at least one coordinate direction of a coordinate system; (b) from said magnetic resonance signal received by said local antenna, deriving a curve of intensity values that are spatially resolved along said coordinate direction; (c) generating a function curve approximating said sensitivity profile of said local antenna, said function curve having a maximum; (d) adapting said function curve to fit said curve of intensity values at a best fit location along said coordinate direction; and (e) identifying a position along said coordinate direction of said maximum of said function curve at said best fit location, as the position of said local antenna along said coordinate direction.
