High frequency imaging
Eye and skin imaging, dental applications, genetics

Imasonic develops high frequency piezocomposite transducers up to 20MHz for innovative and high performance applications.

These single element or array transducers are custom designed, some examples are illustrated below :

High frequency single element transducers for eye imaging

  • 20MHz focused transducer
  • Very high sensitivity
  • High beam pattern predictability
Example of 20MHz single element transducer

High frequency 1D or 2D arrays

  • Focusing with or without focusing lens
  • High sensitivity : elementary loop gain -22dB
  • Bandwidth 70%
  • Optimised anti reverberation
  • Low cross coupling between neighbour elements : -40 dB
Example of 10MHz 128ch linear array
