Abstract

In a method for the location determination of a positionable object in an examination subject by means of magnetic resonance and apparatus for the implementation of the method a reference image is acquired from at least one slice of the examination subject. The current position of the subject is determined by at least one radio-frequency reception coil attached to the object. A slice position in which the reference image is updated is determined on the basis of this current position.
