Offset-mode CT scan of an apple using table-top PHYWE scanner
<p>This is an X-ray dataset from a table-top PHYWE instrument recorded at the CINEMAX Summer School on 3D Imaging, August 2021, Fuglsang Manor, Lolland, Denmark.</p><p>The scanner was operated in offset mode, ie the centre-of-rotation was deliberately moved to the side to enable a larger field of view to image an object larger than the instrument's normal field of view, using a 360 degree scan. The object scanned is an apple collected in the Fuglsang Manor garden.</p><p>The data contains, in the raw/ folder the raw projections and in the reconstruction/ folder the reconstructed slices computed by the instrument's own software. These reconstructed slices do not contain the full apple and also shows double illumination from the offset scan geometry.</p><p>The file settings.cto contain all required geometrical information to set up the geometry for reconstruction using other software.</p>

Seismogenic process of fluid injection revealed by in situ dynamic CT scanning
<p>In the process of unconventional energy exploitation, large volumes of fluid are injected into low permeability reservoirs for hydraulic transformation to generate a fracture network conducive to fluid migration. Unfortunately, extensive fluid injection can induce earthquakes, endangering human lives and causing serious economic losses. Understanding the seismogenic process of fluid injection within a reservoir helps to minimize the induced earthquakes. To better monitor the deformation changes in reservoirs, we conducted in situ dynamic X-ray computed tomography (CT) during a series of experiments lasting 3 minutes for real-time identification of the location and geometry of hydraulic fractures and found that the seismogenic process of fluid injection with a wide range of frequencies is triggered by water–rock interactions.</p> <p>The data we uploaded can be divided into two main parts. The first part is the confining, axial and water injection pressures recorded during the hydraulic fracturing experiment. The second part is the CT scans of the rock sample during the hydraulic fracturing experiment.</p>
