Although, soft tissue contrast of MRI is effectively high, visualization of the internal devices, such as guidewires and catheters, is not straight forward. In order to achieve better identification of these devices, various tracking techniques have been developed. Passive tracking methods are easy to implement, but they are not sufficiently reliable. The main problem of active tracking techniques is uneasy device handlings. They need to be connected to imager with cables. In addition, these cables create safety problems. There are also hybrid methods, using inductively coupled RF (ICRF) and receive coupled RF (RCRF) coils. In our study, we propose a new method using ICRF coils and transmit array system. Presented method enables simultaneous acquisition of anatomy and catheter images.
