IMPLOSION TECHNIQUES FOR ULTRASOUND

摘要

A housing (50) is placed on skin of a subject, and draws at least a portion of the skin within at least a part of the housing. The housing includes at least first and second support structures (34), placed in contact with a surface of skin surrounding the portion of the skin, the first support structure having a first concave surface (153) and the second support structure having a second concave surface (153) that faces the first concave surface. The apparatus includes one or more first ultrasound transducers (160) coupled to the first support structure and one or more second ultrasound transducers coupled to the second support structure. The apparatus also includes a control unit which drives the first and second ultrasound transducers to induce an implosion wave in a target region of the skin. Other embodiments are also described.
