From: The first observation of 4D tomography measurement of plasma structures and fluctuations

(a) Temporal evolution of the total emission and (b) two-dimensional images of emission at the three axial positions during the relaxation phase, z = 0.35, 0.60, and 0.85 m. The images are obtained using the FBF fitted to MLEM profile. The dashed circles indicate the plasma boundary.
