1. 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 of a magnetic resonance tomography system, wherein the MR local coil unit has at least one coil element, a reference sensor system and at least one acceleration sensor spaced apart from the reference sensor system in a fixed relative position, the method comprising:
providing a first 3D relative position of the reference sensor system in relation to the main magnetic field;
receiving an acceleration vector from the at least one acceleration sensor;
retrieving a distance vector describing the 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.
