Medical Power Ultrasonic Transducer: Spherical Annular Array and Acoustic-Lens Focusing.
An English-language introduction to medical power ultrasonic transducers and two methods for concentrating acoustic energy at a controlled focal region.
Focused Ultrasound
Transducer architecture determines how acoustic energy is concentrated.
Piezoelectric elements convert electrical excitation into ultrasonic vibration. A spherical annular array controls the active aperture through concentric elements, while an acoustic lens shapes the wavefront through its geometry and material properties. Both approaches support energy concentration near a selected focal region.
