We have studied C-mode and B-mode imaging using high-frequency ultrasonic waves through a thin fiber for direct observation of the microscopic image of tissue. We reported previously that the C-mode images of the tissue on the glass and B-mode image of animal bone placed in water were obtained using a fused quartz fiber as the needle-type ultrasound probe. In this paper, we propose a method for the...
We have studied transmission methods of high-frequency ultrasonic waves through a thin fiber for direct observation of the microscopic image of the tissue. We reported that high frequency ultrasonic waves (70 – 175MHz) transmitted approximately 1.6mm in the acoustic coupling medium, and a C-mode image of a coin placed in water was obtained using a tapered fused quartz fiber as the probe. In this paper,...
