Clinical ultrasound, photoacoustic, and fluorescence image-guided lymphovenous anastomosis microsurgery via a transparent ultrasound transducer array.

ABSTRACT: Multimodal optical and ultrasound imaging (USI) provides complementary diagnostic insights. However, because conventional USI uses opaque ultrasound (US) transducers, integrating these two modalities results in a bulky and complicated handheld probe in which neither modality performs efficiently. Although transparent ultrasound transducers (TUTs) solve these issues by acting as optical windows, enabling the seamless combination of light and US beams, single-element TUTs are not common in clinical environments. Here, we demonstrate a clinical triple-modal US, photoacoustic, and fluorescence imaging system, seamlessly integrated via a linear TUT-array. This system, with 64 channels and a 7-MHz center frequency achieves 72.7% optical transparency in the near infrared region. The system's hand
