Abstract
A medical ultrasound array transducer assembly for achieving two-dimensional phase correction of an aberrated ultrasound beam is disclosed. The array transducer assembly comprises a plurality of transducer elements and is configured for insertion in or contacting to the human body. The two-dimensional phase correction comprises mechanically correcting ultrasound beam phase errors in a first dimension, and electronically correcting ultrasound beam phase errors in a second dimension. The transducer array assembly requires significantly fewer channels than a standard array which used for two-dimensional phase correction.
