30 MHz High-Frequency Linear Array for Ocular Elastography
The HFU-30 is a high-frequency linear array transducer engineered for ultrasound elastography of anterior ocular structures. This custom-built 256-element array operates at 30 MHz and utilizes an interdigitally bonded piezo-composite design to achieve high-resolution imaging of the cornea and ciliary body. When integrated with a mechanical shaker-based elastography system, the HFU-30 enables precise tracking of elastic wave propagation to assess the linear and nonlinear biomechanical properties of ocular tissues under varying intraocular pressure. This technology provides critical insights for understanding glaucoma pathogenesis and identifying high-risk patients.
