Recently, there's been an increase of research into spontaneous three-dimensional deformation of torus plasmas. In this study, it is aimed to observe the three-dimensional dynamics of plasmas by reconstructing the bremsstrahlung soft X-rays emitted from high-temperature plasmas using a multiple-pinhole camera. In this presentation, the three-dimensional tomography method is applied to the torus plasma device, named RELAX, and the results are compared with the edge magnetic field fluctuation measured by magnetic probes.
