The contribution presents current status and development of tomography tools in the Institute of Plasma Physics of the Czech Academy of Sciences (IPP Prague). The tomography package, based on Minimum Fisher Regularisation (MFR) algorithm, has been recently maintained and optimised in the Python environment. It allows for fast and robust reconstruction of plasma emissivity profiles from line integrated measurements (plasma projections) provided e.g. by the pinhole cameras. On the COMPASS tokamak, MFR serves in analyses of soft X-ray (SXR) radiation and of wide spectral range of radiation measured by AXUV photodiodes.
