The multi-mode intravascular coil consists of a single active device that is connected to the external system via a single coaxial cable and performs three functions: 1) active tip tracking, 2) imaging and 3) inductively coupled wireless marker. The coil behaves as a pseudo transmit coil due to coupling with an external transmit coil. The variable conductor density design of the multi-mode coil results in variable B1 field magnification in its vicinity. This provides an opportunity to adjust transmit power for optimal operation of the multi-mode coil in all three of its functional modes.
