The Biomedical Ultrasound Lab develops high-frequency ultrasound composite and single-crystal ultrasound transducers and arrays using MEMS technology for various biomedical imaging applications. The lab is the first to have developed high-sensitivity PMN-PT single-crystal transducers for ultrasound and photoacoustic imaging, including intravascular imaging, cancer imaging, and ophthalmic imaging. The team is also developing a novel imaging tool for characterizing elastic properties of retinal and corneal tissue by acoustic radiation force-induced optical coherence electrography. Additionally, the lab is investigating high-resolution ultrasonic elastographic imaging techniques using high-frequency ultrasound. The lab is also actively exploring ultrasonic-mediated therapeutic technology including trans-sclera drug delivery, as well as ultrasound for retinal and brain stimulation.
