Abstract
An ultrasound probe particularly for diagnostic purposes includes a first array of ultrasound transducers that generate ultrasound waves by electric excitation and transforming ultrasound waves impinging on them into electric signals. Each transducer is provided with contact electrodes which are connected respectively to a ground potential and to electric signals feeding lines. The first array of transducers includes emitting transducers and is intended only for generating and transmitting ultrasound waves, while a second array of transducers is provided over the first array of emitting transducer and includes receiving transducers for generating the electric receipt signals. The second array of transducers is formed of a material having piezoelectric behavior.
