Two-dimensional arrays are required to implement an electronic two-dimensional phase correction in tissue. Instead of using a two-dimensional array, a new technique is proposed which uses a deformable transducer of significantly fewer channels for two-dimensional phase correction. Phase correction in azimuth is achieved by altering the electronic phase delay of the element. However, phase correction in elevation is achieved by tilting the element in elevation with a piezoelectric actuator. In this paper, simulations of the deformable array and results from a prototype deformable array will be presented.
