A Novel Matching Layer Design for Improving the Performance of Transparent Ultrasound Transducers.
IEEE Trans Ultrason Ferroelectr Freq Control

Article Synopsis
- Transparent ultrasound transducer (TUT) technology helps align optical and acoustic signals for compact photoacoustic imaging but struggles with narrow bandwidth and low sensitivity due to inadequate matching layers.
- The study investigated the use of translucent glass beads in transparent epoxy as an effective acoustic matching layer for TUTs, revealing improved pulse-echo sensitivity and bandwidth.
- This matching layer not only enhances performance but also acts as a light diffuser for better optical uniformity on tissue, is cost-effective, easy to produce, and compatible with soft tissue.
