Reconstructed data - This dataset contains the reconstructed image data. Each sub-folder contains a set of 2D slices that together make up a 3D image from that time point. Not all images from all datasets have been reconstructed, the values in parentheses refer to the scan numbers that have been reconstructed. Raw data - This dataset contains the raw unprocessed image data collected during the development of the XRheo system. Processed data - This dataset contains the post-processing outputs from analysis of the data from the XRheo development experiments. Each sub-folder contains the files generated during filtering, segmentation and separation of the features [M (melt), B (bubbles), X (crystals)], and the post processing analysis for size distributions and tracking. The data sets included are the results of dynamic X-ray tomography experiments performed on multiphase synthesised magmas being deformed under known temperature and strain rates for a concentric cylinder geometry.
