ULTRASOUND TRANSDUCER FOR MEDICAL USE

摘要

The invention relates to a phased-network ultrasound transducer for medical use, comprising a single support (2) and a group of transducer elements (3) distributed randomly on the surface of the support (2), said transducer elements (3) being fixed. According to the invention, the group comprises at least two sub-groups of transducer elements (3), each of said sub-groups having a different geometric point of convergence such as to focus an ultrasound energy in a different coverage volume (4, 5) such that the arrangement of said coverage volumes covers a target volume to be treated. In addition, the invention includes control means for controlling the transducer elements (3) independently of one another.
