Abstract

A medical apparatus, includes a medical instrument with an acquisition unit for a magnetic resonance signal, the acquisition unit exhibiting a non-constant sensitivity profile in the azimuthal direction relative to an axis of the medical instrument. An azimuthal orientation of the medical apparatus is determined by an evaluation unit from magnetic resonance signals received by the acquisition unit.
