Abstract :
We have studied to transmit the high-frequency ultrasonic waves in a thin fiber for direct observation of the microscopic image of the tissue. In the latest experiment, we observed the reflected wave from the end of the fiber at the frequency of approximately 160 MHz, and the transmitted waves in the frequency from approximately 160 MHz to 100 MHz through the acoustic coupling medium. In this study, we report that the reflected waves (echoes) from a reflector through the acoustic coupling medium using a tapered fused quartz fiber could be detected.
