Abstract
The present disclosure provides an ultrasound transducer (UT) assembly for ultrasonic and photoacoustic dual-mode imaging of an endoscope, including a UT and a microlens integrated in the UT. The microlens is used for beam collimation or focusing and accommodated in an aperture of the UT. A probe/catheter including the UT assembly, an endoscopy system including the probe/catheter, and a method of manufacturing the UT assembly are also provided. The present application uses a photocurable glue and mold to form the microlens integrated in the UT and adopts the coaxial arrangement of the devices to solve the problems of light supply and device dimensions (rigid length and diameter), thereby simplifying the manufacturing process of intravascular photoacoustic (IVPA) probe/catheter.
