An ultrasound transducer assembly (30) is disclosed, comprising: a plurality of ultrasound transducer elements (34, 36, 38) for receiving ultrasound waves and for providing transducer signals (X2, X3, X4) corresponding to the respectively received ultrasound waves. The assembly comprises a plurality of signal combiners (42, 44; 60, 62, 64) for providing different output signals (Y1, Y2) on the basis of the transducer signals, and a plurality of timing elements (48, 52; 68, 70; 72, 74) for providing different time shifts (τ) to the transducer signals. Each of the ultrasound transducer elements is connected to a plurality of the signal combiners for providing the transducer signals including the different time shifts to different of the signal combiners.
