High power
and therapeutic ultrasound
Imasonic high power technology
Typical features
The figures mentioned below are indicative and shall
be considered in a precise environment and for a given application.
Other important parameter, like thermal environment,
acoustical coupling, duty cycle and other electrical and acoustical
conditions shall be defined in order to determine the rights technological
solutions and the performances the transducer should have.
| Maximum acoustic power (surface)* |
up to 30 W/cm² |
| Efficiency |
50 to 70% |
| Frequency range |
200 KHz to 10 MHz |
| Shaping capabiliity |
F number down to 1/2 |
| Size range |
up to 300 mm diameter |
| Array capability |
yes |
| Bandwidth |
30 to 70% |
| MRI compatibility |
yes, on request

For high power and therapeutic applications Imasonic
designs and produces single elements and transducer arrays including
annular arrays, 1D and 1.5D linear arrays and 2D matrix arrays.
Transducers can be designed with simple housing or dedicated housing
for MRI compatibility, endocavitery laparoscopic or peroperative
applications.
