There are many techniques considered in the literature to reduce RF heating. A small number of passive RF traps incorporated in the reception cable present excellent results in the case of an endoluminal coil at 3T. The historical design of RF trap such as LC filters is efficient. Due to the distribution of induced currents in the cable, a close attention should be paid to the location of the RF traps along the cable. Optimal placememt can also narrow down the number of RF traps to a minimum.
