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.
