Research on Impermeable-materials with the Elastic Wave CT Image Reconstruction of Quality of Cutoff Wall Based on SIRT Algorithm

摘要

take the travel time distribution of elastic wave of engineering medium acquired by using elastic wave CT technology when the engineering quality testing as the research object, select the SIRT technology to complete inversion of wave velocity data to construct distribution image of wave velocity. The main content of the research is inversion techniques of CT data. Key technology is to introduce Fluorescence Molecular Tomography based on ray equation or wave equation, and carry out the iterative reconstruction of data, calculate the travel time distribution of elastic wave in the project media into wave velocity distribution, so that the image has a clearer description about detected object. Establish a set of elastic wave CT data imaging inversion platform, and make the CT image reflect the actual project quality more realistically through image optimizing.
