Harmonic Imaging
For harmonic imaging, echoes at
harmonics of the fundamental frequency are detected.
These harmonics are generated
by non linear acoustic properties of tissues, and allow better
images on technically difficult patients, combining the penetration
of fundamental frequency and resolution of harmonics
This technique requires transducers
with frequency spectral adapted to emitting frequency f and receiving
frequency 2f
Imasonic developes and
manufactures transducers for harmonic imaging, exploiting
its capacity to design and predict specific spectral profiles,
and to manufacture corresponding transducers
