A study for real-time B-mode imaging using 100-MHz-range ultrasound through a fused quartz fiber

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 real-time B-mode imaging, and show experimental results.
