Abstract
Novel sparse array structures are described which greatly reduce the total number of independent transmit and receive elements in the array without significantly degrading imaging performance. Periodic sparse transmit and receive arrays, one with a first spacing between elements or groups of elements and the other with a different spacing between elements or groups of elements, are combined through interpolation to create a sparse array having imaging capability comparable to that of an equivalent dense array.
