1. A method for scanning within a three dimensional volume, the method comprising:

  • (a) switchably interconnecting at least first and second elements of a two-dimensional array of elements and a system channel, the at least first and second elements comprising a first macro element;

    (b) forming a first beam at an angle other than normal to the two-dimensional array of elements using at least the first macro element and the system channel, the first beam within a first plane responsive to the first macro element; and

    (c) switchably interconnecting the first element with a third element of the two-dimensional array of elements, the first and third element comprising a second macro element corresponding to a second plane at a non-orthogonal angle to the first plane.
