| Abstract | This research has been developing an optically switchable resonance circuit to be mounted on the tip of the heart. catheter for the use in nuclear magnetic resonance (NMR) system. For resonance circuit to be detectable, the resonance frequency of the circuit must be equal to the resonant frequency of the NMR system. The microcoil, a component of the circuit was manufactured by using micromachining with the use of UV-LIGA technique. The advantages of microsystem are good reduction in size, good reproducibility and high accuracy with the high aspect ratio structures. The research had optimized the best microcoil design with high quality factor that has the elliptical shape regarding to higher inductance. The measurement has shown great difference of the quality factor which is much lower from the simulation and the computation due to long bong wires and poor circuit connection. Nevertheless, with the use of optical switching ability, the catheter tip can be detected under the NMR system. The whole system can be further used in parallel with the minimal invasive surgery |
