Abstract
A downhole tool can be deployed having an acoustic transducer array having a plurality of electroacoustic elements disposed circumferentially about the downhole tool, i.e., arrange in a circular shape. The acoustic transducer array can operate by activating active apertures to create synthesized acoustic pulses and receive the pulses' echoes, i.e., acoustic reflections, and then, in cooperation with one or more processors, create a 360° image of the casing and material behind the casing.
