Abstract
In a method and magnetic resonance device for graphically assisting the navigation of an instrument (in particular a medical instrument such as a needle and/or a guide sleeve guiding a needle) within a procedure region of a target subject (in particular a patient), coordinates of a target position and/or target region to be addressed that are obtained from a high-contrast image data set acquired with the magnetic resonance device. Low-contrast image data showing the instrument are acquired continuously and/or intermittently during the navigation and/or the position and orientation of the instrument is determined (in particular measured) with a position determination device. The low-contrast image later are brought into registration with the magnetic resonance device continuously and/or intermittently during the navigation. A representation showing at least the relative position and orientation of the instrument relative to the target position and/or target region is generated and displayed under consideration of the coordinates and the low-contrast image data and/or the position and orientation of the instrument.
