Computed Axial Tomography (CAT) Scan

A CAT (computed axial tomography) scan animation is included because seismic tomography is often compared to CAT scans. Both techniques have an energy source (seismic tomography uses the energy generated from earthquakes; CAT scans use x-ray energy) and a receiver (seismic tomography uses seismograph stations; CAT scans use computers) that records the data.
