Abstract
In a method for detecting rotational orientation and position tracking of an inductively coupled RF (ICRF) coil using a transmit array system, a conventional body birdcage coil is used, but the quadrature hybrid is eliminated to use the two excitation-channels separately. The transmit array system provides RF excitations such that the body birdcage coil creates linearly polarized and circulating RF pulses instead of a conventional rotational forward polarized excitation. Inductively coupled RF (ICRF) coils can be constructed on catheters for detecting rotational orientation and tracking purposes. The modifications on anatomy and ICRF coil images are different due to the RF excitation scheme such that the ICRF coil can be separated from the anatomy in real-time. After separating the ICRF coil from the anatomy, a color-coded image can be reconstructed, for example.
