Researchers at Pohang University of Science and Technology (POSTECH) have developed a novel transparent ultrasonic transducer (TUT) that significantly enhances the performance of ultrasound-photoacoustic dual-modal imaging systems. Published in Nature Communications, their research addresses the integration challenges of conventional ultrasound and optical pathways by using a silicon dioxide-epoxy composite to achieve high optical transparency (>80%) while maintaining robust acoustic performance. This advancement allows for real-time, high-resolution imaging with depth-to-resolution ratios three to six times higher than traditional systems. The new TUT could improve various medical and technological applications, from imaging to laser surgery and beyond.
