HIFU Transducer: High Intensity Focused Ultrasound
BII's HIFU transducers (high intensity focused ultrasound) consist of bowl aperture with focal point or cylindrical sector with focal line for physical, chemical, biological, thermal and high-stress uses in nonlinear underwater acoustics: cavitation, streaming, sonic processes and HIFU R&D. The focus of linear or annular array can be manipulated with array beamforming (Beam Steering and Focusing). BII provides custom-fit designs on frequency, geometric focus, Fresnel number, focal diameter, length and intensity for industrial, biomedical, marine and research applications. Please contact BII for information on MRI compatibility or safety.
