The term for a transducer that has an array of rec-
tangular elements arranged in a straight
line is
A. Annular array
B. Linear array
C. Curved array
D. Oscillating mechanical transducer
E. Convex sequenced array
D. Mechanical focusing
9. For a linear array transducer consisting of a
single row of elements, what method is most The Z axis is also known
used to focus the beam in the elevational as the out of plain
direction dimension. It is the axis
A. Transmit focus that runs across the width
B. Dynamic receive focusing of the transduc- er
C. Aperture focusing transmit, dynamic receive
D. Mechanical focusing an aperture focusing
E. None of the above require the use of
multiple elements. Since
there are not multiple
elements along the
width of the transducer,
these types of focusing
cannot be ac-
complished in this
