Design and Fabrication of Double-Focused Ultrasound Transducers to Achieve Tight Focusing

Autor: Jihun Jang, Jin Ho Chang

Publikováno v: Sensors, Vol 16, Iss 8, p 1248 (2016)

Beauty treatment for skin requires a high-intensity focused ultrasound (HIFU) transducer to generate coagulative necrosis in a small focal volume (e.g., 1 mm3) placed at a shallow depth (3–4.5 mm from the skin surface). For this, it is desirable to
