Abstract

The invention discloses a high frequency ultrasonic energy transducer with optimized performance and a manufacturing method thereof; the energy transducer comprises a backing layer, a piezoelectric layer and a matching layer connected in sequence; the backing layer is a glue mixture doped with granular material and/or the matching layer is a granular material doped glue mixture and/or a poly-p-xylylene film. The method comprises the following steps: casting the glue mixture doped with granular material on one side/two opposite sides of the piezoelectric layer so as to form the matching layer and/or backing layer; grinding solidified matching layer and/or backing layer to a preset thickness. The other method comprise the following steps: plating the poly-p-xylylene on one side of the piezoelectric layer so as to form the matching layer and/or casting the glue mixture doped with granular material on the other side of the piezoelectric layer so as to form the backing layer. The high frequency ultrasonic energy transducer and the manufacturing method thereof can prevent the generation of a glue bonding layer, so the matching layer and/or backing layer and the piezoelectric layer can be better matched, and wider bandwidth is realized, thus optimizing propagation efficiency of the sound wave energy.

Description

technical field [0001] The invention relates to an ultrasonic transducer, in particular to a performance-optimized high-frequency ultrasonic transducer and a manufacturing method thereof. Background technique [0002] Intravascular Ultrasound (IVUS) is a new diagnostic method combining non-invasive ultrasound technology and minimally invasive catheter technology. Intravascular ultrasound is the use of catheter technology to introduce a high-frequency micro-ultrasound transducer into the coronary artery cavity for detection, and obtain cross-sectional imaging of each layer of the vessel wall to assist clinicians in diagnosing intravascular lesions. [0003] The intravascular ultrasound imaging system includes three main components: an intravascular ultrasound catheter equipped with an ultrasound probe, a retraction device, and an ultrasound host. The intravascular ultrasound catheter works directly in the blood vessel and is the core component of the entire imaging system. T...
