Outline of Final Research Achievements

An electromagnetic scanning forward viewing ultrasound thin endoscope intended to be equipped in a guide wire has been developed for intravascular treatment. The endoscope consists of a resonator with an ultrasonic transducer and a driving coil. Driving of the electromagnetic resonator was confirmed using the driving coil, 50 um witdth silicon beam and a cylindrical shaped samarium cobalt magnet. Almost element technology has been established for fabrication of the device and equipment in the guide wire and ultrasound imaging will be realized by packaging in thin and small size.
