system for multiple frequency imaging of the patient tissue using intravascular ultrasound imaging system

摘要

Method for imaging a patient tissue using intravascular ultrasound images comprises inserting a patient blood vessel (102) catheter. The catheter includes one converter and (312) at least being constructed and arranged towards the insertion into the lumen of the catheter. In between incremental rotation of the one transducer, the acoustic signal is transmitted to the patient tissue along a series of scan lines from the transducer of the at least one. Transmitting an acoustic signal, acoustic having a second frequency bandwidth of the second centering acoustic signal having a first frequency bandwidth of the first around the first center frequency, the center frequency of the second I and a signal. Echo signals corresponding reflected from patient tissue is received, deformation, processing, and display. [Selection] Figure Figure 1
