Numerical simulations: estimated cardiac and respiratory motion obtained from one simulated EAM point signal.

<p>The simulated catheter location (a,b,c) was obtained by combining the cardiac motion model (d,e,f, blue) and the respiratory motion model (g,h,i, blue). Cardiac and respiratory motions were then estimated from the simulated catheter location and are shown in (d,e,f, red) and (g,h,i, red), respectively. The proposed approach provided an accurate demodulation of cardiac and respiratory motion components in all three spatial dimensions.
