We developed new miniature 2D array ring transducers integrated into interventional device catheters such as deploy atrial septal occluders. One transducer consisted of 55 elements operating near 5 MHz. The interelement spacing is 0.20 mm. It was constructed on a flat piece of copper-clad polyimide and then wrapped around an 11 French catheter. We used a braided wiring technology from Tyco Electronics Corp to connect the elements to our real-time 3D ultrasound scanner. Typical measured transducer element bandwidth was 20% centered at 4.7 MHz. We built another 55 element transducer with a single matching layer. The matching layer is from EBL Products, Inc. and is the #107 matching layer,.19 mm thick. The matching layer plate was metallized on both sides with 500 Å of nickel and 1000 Å of gold prior to bonding to the PZT layer with Epotek 301 Epoxy. The resulting average bandwidth was 60% centered at 4.4 MHz. © 2011 IEEE.
