• We have developed an imaging system that applies FM-chirp pulse compression technology for use in intraductal ultrasonography, or intravascular ultrasonography. The pulse compression technique attempts to raise resolving power by using average power effectively under peak power restriction. This paper describes a method that use pulse compression technology in intravascular ultrasonography. In this paper, the following are reported: 1) A method to use the FM-chirp pulse compression technique in an imaging system is proposed. 2) A transmission line suited for intravascular ultrasonography is constructed using the L(0, 1) mode of the Pochhmmer-Chree wave propagating in a fused quartz rod coated with carbon. 3) A receiving signal from a target is compressed to give a shot pulse.
