Ultrasonic transducer chip assembly, ultrasound probe, ultrasonic imaging system and ultrasound assembly and probe manufacturing methods

Abstract

Disclosed is a method for manufacturing an ultrasonic transducer assembly comprising an ultrasonic transducer chip having a main surface comprising a plurality of ultrasound transducer elements and a plurality of first contacts for connecting to said ultrasound transducer elements, a contact chip having a further main surface comprising a plurality of second contacts, a backing member comprising ultrasound absorbing and/or scattering bodies, said backing member comprising a first surface on which the transducer chip is mounted and a second surface on which the contact chip is mounted. A flexible interconnect extends over said backing member from the main surface to the further main surface, the flexible interconnect comprising a plurality of conductive tracks, each conductive track connecting one of said first contacts to a second contact. An ultrasound probe including such an assembly, an ultrasonic imaging system including such an ultrasound probes and manufacturing methods of such an assembly and probe are also disclosed.
