ABSTRACT:
An ultrasound transducer assembly for use in a phased array ultrasound imaging system includes an array of ultrasound transducer elements having a two-dimensional transmitting and receiving surface that is curved in at least two orthogonal directions and conductors for connecting the transducer elements to electronic circuitry of the ultrasound imaging system. The array may include a curved, two-dimensional array of rows and columns of transducer elements. The transmitting and receiving surface is typically convex but may also be concave. The transmitting and receiving surface may be a portion of a spheroid or an ellipsoid. In one embodiment, the transmitting and receiving surface is configured as a portion of a spherical surface.
