One of reverse time migration's main limitations is that an unscaled adjoint operator is prone
to produce images with low resolution, inaccurate amplitudes, and even artifacts. Least …

The ultrasonic echo technique is widely used in non-destructive testing (NDT) of concrete
objects for thickness measurements, geometry determinations and localization of built-in …

The ultrasonic echo technique is frequently used in non-destructive testing (NDT) of
concrete structures for thickness measurements, geometry determinations as well as …

In this work, the highly accurate image of a defect in the layered media using a reverse time
migration (RTM) is obtained without priori information of the interface geometry and acoustic …

The ultrasonic echo technique is broadly applied in non‐destructive testing (NDT) of
concrete structures involving tasks such as measuring thickness, determining geometry and …
