In this study, we aim to improve the safety and the performance of intravascular ultrasound (IVUS), we proposed a technique to construct an IVUS probe with super-small diameter through the development of the ultra-small ultrasound motor. Additionally, we proposed an actually available ultrasound transmitting/receiving system required for much detailed imaging using the proposed IVUS probe, which is examined from both aspects of hardware and transmitting/receiving schemes. We also developed several signal processing techniques for observed echo signals, and enabled further high quality imaging.
