Application of the First Arrival Waves Automatic Extraction Transformation and Process Optimization in Cross-hole Elastic Wave CT

The main applications of CT technology in geophysics are electromagnetic wave CT and elastic wave CT. Elastic waves tomography based on ray tracing theory is one of the important engineering geophysical methods. It has been widely used in engineering quality inspection and engineering survey. The research has summarized a set of more efficient post-processing processes and developed data pre-processing software to reduce the post-processing workload and provide a solution and method for other researchers.
