MRI-guided RF ablation is a promising method for guiding
and conducting thermal therapies such as
electrophysiology (EP) procedures and relies on accurate
temperature monitoring. Proton resonance frequency (PRF)
shift MR thermometry, which is the choice of method, is
very sensitive to motion. In this work, a novel method
that employs active tip tracking coils and Extended
Kalman Filter is proposed for motion prediction and
compensation. Compared with previously described MR
thermometry methods, the proposed method can be
particularly advantageous for correcting through-plane
motion.
