Focused ultrasound transducer tracking is of great significance in various new Magnetic Resonance guided Focused Ultrasound (MRgFUS) applications like in pain palliation of bone metastases and prostate tumor treatment. In this work, a navigator based novel method is described to demonstrate the feasibility of transducer tracking without the micro RF-coil setup. The algorithm is verified experimentally and provides highly accurate estimates, thereby making it suitable for the new applications. A novel tracking pulse sequence is also developed for the same, which is interleaved within the main thermal imaging pulse sequence.
