Abstract

Conventionally an A-mode scan, a single measurement
with a single element transducer, is only used to detect the
depth of a reflector or scatterer. In this case, a single measurement reveals only one-dimensional information; the axial distance.
However, if the number of scatterers in the ultrasonic field is sparse, it is possible to detect the location of the scatter in multiple spatial dimensions. In this study, we developed a method to find the location of a scatterer in 3-D with a single-element transducer and single measurement. The feasibility of the proposed method was verified in 2-D with experimental measurements.
