HIFU Transducer: High Intensity Focused Ultrasound
BII's HIFU transducers (high intensity focused
ultrasound) consist of bowl aperture with focal point
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.
