Evaluation of noise and blur effects with SIRT-FISTA-TV reconstruction algorithm: Application to fast environmental transmission electron tomography.

•The proposed SIRT-FISTA-TV algorithm is adapted to tomography reconstruction from tilt series of images such as recorded in Transmission Electron Microscopy. It produces reconstructed volumes with clear and sharp edges, and thus, the segmentation step was quite easy to perform after 3D reconstruction.•SIRT-FISTA-TV can suppress noise artifacts without affecting spatial resolution.•SIRT-FISTA-TV is robust to blurred data and gives better results than conventional reconstruction algorithms.•SIRT-FISTA-TV is very well adapted to 3D reconstruction of experimental data (i.e. tilt series of projections) collected during very rapid tilt series acquisitions (down to 5 seconds) in situ or operando environmental TEM for studying dynamics of nanomaterials such as nanocatalysts.
