Original Kurzfassung:
We present the theory and some applica-
tions of the synthetic aperture focusing technique applied
to single transducer ultrasonic data sets. In this tech-
nique a virtual source located at the geometrical focal
point of the physical transducer is algorithmically gen-
erated and thus allows for tighter focusing over a geo-
metrically larger scan volume. We present results from
a structural test phantom (two copper wires) and a de-
laminated specimen.
