A method of scanning using a two dimensional (2D) ultrasound transducer array having at least one row of ultrasound transducer elements configured to extend in a curved dimension of the array and at least one column of ultrasound transducer elements configured to extend in a linear dimension of the array, the method comprising:
- defining a sub-aperture of the ultrasound transducer array that includes a plurality of ultrasound transducer elements in the curved dimension of the array and a plurality of ultrasound transducer elements in the linear dimension of the array;
- and
- exciting the ultrasound transducer elements included in the sub-aperture to generate a transmit/receive ultrasound beam.
