14. A method for detecting an outer contour of an object by a magnetic resonance tomography unit that includes a patient tunnel that has a longitudinal direction and into which the object is inserted and a patient couch with which the object is moved in the longitudinal direction in the patient tunnel, the method comprising:
moving the patient couch in relation to the longitudinal direction in the patient tunnel in a transversal direction into a left-hand side extreme position and an opposite-lying right-hand side extreme position;
acquiring a right-hand side image including a right-hand side part of the outer contour of the object on the patient couch in the left-hand side extreme position;
acquiring a left-hand side image including a left-hand side part of the outer contour of the object on the patient couch in the right-hand side extreme position; and
creating the outer contour of the object from the left-hand side part of the outer contour and from the right-hand side part of the outer contour.
