A hydrogel acoustic coupling medium was investigated as a practical alternative to water for clinical applications of focused ultrasound (US) therapy. Material characterization and functional testing of polyacrylamide gel couplers were performed. Acoustic, bulk and thermal properties were measured. Conical couplers were designed and fabricated to fit a 3.5-MHz, spherically concave transducer for functional tests, including Schlieren imaging, power efficiency measurements and in vivo hemostasis… CONTINUE READING
