| Research Abstract |
The purpose of this research is realization of high-resolution imaging of local area tissue in the human body using an intra-corporeal MRI/NMR probe fabricated using photoresist pattering and Cu electroplating on the cylindrical substrate. Performance of imaging is improved by multilayered coil pattern fabricated by repeating the process after coating of nonconductive layer. Small size integrated circuits of variable capacitor which can compensate frequency shift by tissues around the coil have been designed and fabricated. Signal receiving of NMR signal was confirmed and image estimation was performed using the mounted circuit on the probe. Receiving NMR signal and imaging without electric breakdown of the integrated circuit was realized using developed protecting circuit.
