Abstract
A method for ascertaining at least one of a position or an orientation of an MR local coil unit for arrangement inside a main magnetic field includes providing a first 3D relative position of a reference sensor system in relation to the main magnetic field; receiving an acceleration vector from at least one acceleration sensor; retrieving a distance vector describing a fixed relative position as a function of the received acceleration vector; calculating a second 3D relative position of the at least one acceleration sensor in relation to the main magnetic field based on the first 3D relative position and the retrieved distance vector; and ascertaining the at least one of the position or the orientation of the MR local coil unit using the first 3D relative position and the second 3D relative position.
