Abstract

Abstract

En 中文
• A reverse-time migration method based on adjoint-tomography theory is developed. • Material-based imaging conditions are explored in drilled hole ultrasound imaging. • Longitudinal wavespeed imaging condition best sizes large-midsize holes. • Density and impedance imaging conditions best sizes smallest holes. • In comparison to total focusing method, cross-correlation methods more specialized.
