A study for propagating ultrasound through transmission line based on cascade-connection resonator model

We are aiming to develop a puncture-type ultrasound microscope by which less invasive settled diagnosis can be executed. To provide in vivo high-resolution imaging of a tumor, we need to scan high frequency ultrasound by rotating an acoustic mirror or an ultrasound oscillator at the tip of a probe. As a driving source device for rotating those, we can use our miniature ultrasonic motor. To narrow the probe while maintaining a smooth rotation of the ultrasonic motor, ultrasound energy for the motor has to be efficiently transmitted from a sound source placed outside the body. In this study, we propose an innovative method for propagating ultrasound using an acoustic transmission line.
