WebMar 7, 2016 · Sensitivity analyses, or synthetic reconstruction tests, are the most common method for assessing solution robustness in seismic tomography, and were originally introduced to investigate spatial resolution in inverse problems for which formal resolution cannot be computed due to the large model size (Spakman & Nolet 1988). They involve … WebCAT Scans & Seismic Tomography For lack of a perfect analogy, seismic tomography is often compared to a CT scan (aka “Cat scan” for Computed Axial Tomography). The CT scan uses computers to generate a three-dimensional image from a lot of flat X-ray pictures. The basic idea of a CT scan is this: The X-ray
