| Outline of Final Research Achievements |
In this study, the radio wave type laparoscope is proposed and developed. In the design of the antenna, it is confirmed that the accuracy for the detection of the blood vessel is improved by arranging the receiving antennas in parallel to the transmitting antennas and by stacking the parasitic elements above the fed antenna elements. The phantoms of the blood vessel and the fatty tissue for the measurement were fabricated. In the fatty tissue, although the measured permittivity of the phantom achieved the target value, the difference was observed in between the measured conductivity and the target value. Also, in the blood vessel, the difference was observed in between the measured conductivity and the target value. It is necessary to examine the materials for the conductivity. In the signal processing, it is found that the position sensing of the blood vessel was possible by taking the average of a signal of the receiving antennas placed in right and left of the transmitting antenna.
