摘要：
An imaging assembly for an intravascular ultrasound system includes a catheter, an imaging core, and at least one transducer conductor. The imaging core is insertable into the catheter and extendable from a distal end of the catheter. The imaging core includes a rotatable magnet, a tilted reflective surface, and at least one fixed transducer all disposed in a body. The rotatable magnet is configured and arranged to rotate by a magnetic field generated external to the catheter. The tilted reflective surface rotates with the magnet. The at least one transducer is configured and arranged for transforming applied electrical signals to acoustic signals and also for transforming received echo signals to electrical signals. The at least one transducer conductor is electrically coupled to the at least one transducer and is configured and arranged to extend into the catheter when the imaging core is extended from the catheter.
