  1. Python script kspace_det_edg.py.
  2. Description.pdf presenting:
  • short introduction to the topic,
  • how the code works step by step,
  • sample results with commentary.
  1. Sample FID data in the sems_20190203_03.fid folder.
  2. Sample results illustrations in FigureA.png and FigureB.png.

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).
