Swelling_tablet_fronts_D_k_from_MRI_T2_or_img - Tool for characterizing the swelling of tablets immersed in a solution. Creates time plots and calculates eroding front's diffusion rate D and the rate of the swelling k from time series of either T2-maps or (properly contrasted, e.g. T2-weighted) MRI images in FDF (file format native for Agilent MRI scanners) or Text Image format. This software is suitable for swelling matrix tablets forming a membrane-like structure in contact with the solution in which they are immersed, https://doi.org/10.5281/zenodo.7262466 (https://github.com/BeataWereszczynska/Swelling_tablet_fronts_D_k_from_MRI_T2_or_img).
