https://doi.org/10.1007/978-3-642-94279-2of tissue is a topic of great interest in medical acoustics. Several techniques have been demonstrated through simulation and laboratory experiment to achieve promising results . The purpose of the present paper is to demonstrate the use of acoustic phase conjugation, or more narrowly in th

The present study shows that non-contact imaging is possible, certainly for superficial body regions, provided judicious choices of piezoelectric materials and matching layers are made. In preliminary experiments
