Advantages of piezo-composite transducers
Focus control is an important element in designing a transducer for medical therapy : it is essential to accurately control the treatment zone and to thus protect the healthy tissue.
The intrinsic features of Imasonic’s piezo-composite structure enable radial modes to be reduced, thus favoring the vibration according to the thickness mode. The electro-acoustic response obtained is thus very close to the theory and the acoustic field does not present any hot points outside the focal point. See the illustration below.
