P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage. People who regularly perform tomographic imaging usually shield themselves by standing behind a barrier or wearing special gear which is designed to resist harmful radiation. Going inside the MRI machine is like being in a coffin. I am a little concerned about all the radiation, though, since I have one every year. Quantum tomography can be used for characterizing optical signals, including measuring the signal gain and loss of optical devices, as well as in quantum computing and quantum information theory to reliably determine the actual states of the qubits.
