Abstract

Intravascular ultrasound (IVUS) plays an important role in assessing the morphology of atherosclerotic plaque and the correct placement of stents. However, in the mechanical scanning type IVUS that uses a torque wire to turn a transducer or a reflecting mirror, image distortion due to non-uniform rotation may be a problem. To avoid non-uniform rotation, the use of an electromagnetic motor on the tip has been developed. However, the motor is difficult to miniaturize because it uses a magnet. An ultrasonic motor that uses a helical coil as a stator can be miniaturized (CS-USM). Therefore, we developed a new IVUS system using CS-USM
