About Seismic Tomography

Cross-hole sonic logging (CSL) has become a universal standard, non-destructive testing (NDT) method for evaluating the integrity of foundation structures for maintaining quality assurance and quality control (QA/QC) of transportation facilities and infrastructures. CSL Tomo 3D ™ is a three-dimensional cross-hole sonic logging (CSL) data processing technology that enhances the capabilities of techniques currently used to characterize the interior structure of deep foundation elements and simplifies presentation of the processed data as compared to other methods. The true three-dimensional representation offered by CSL Tomo 3D ™ provides greater detail of the interior structure making defects easier to classify. This paper will present an overview of CSL Tomo 3D ™ and its application for quality assurance/quality control of deep foundation elements
