In most respiratory self-gating techniques, the self-gating signal can be derived from all acquired channels. However, only coil elements close to the diaphragm deliver a reliable signal. Therefore, previous approaches usually required manual selection of an appropriate coil element or fixed scan protocols, both of which is infeasible for clinical routine applications.
