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.
We recently introduced piezoelectric lithium niobate (LN) based transparent ultrasound transducers (TUT) as a new platform for developing multimodal optical, ultrasound and photoacoustic imaging systems. However, LN based TUT is limited in its signal-to-noise ratio due to material's low piezoelectricity ( ). In this paper, we report, for the first time, a 0.

There is a need to develop a platform to facilitate this multimodal imaging capability to improve diagnostic sensitivity and specificity. .
