can be easily implemented by employing proper hard-
ware solutions.
Even though the proposed system is air-coupled
and provides a qualitative imaging of targets support,
it can be easily generalised to the underwater acoustic
imaging case, which represents a convenient, prelim-
inary test before moving to the imaging of human tis-
sues. For instance, in the framework of breast cancer
imaging, the use of this kind of systems could be ben-
eficial for early diagnosis, since it is safe and allows
a frequent screening which may be a complementary
exam to support cancer diagnosis and advancing clas-
sic ultrasound.
Future work will focus on the design and build-
ing of a water-matched prototype for the performance
assessment with breast tissue mimicking phantoms.
