dc.descriptionMARS Spectral Dataen
dc.description.abstractStudies on beam hardening and metal artefact reduction using Medipix All Resolution System (MARS) spectral scanner were carried out. Four datasets are provided - titanium phantom, titanium scaffold, magnesium scaffold and titanium mesh. Each of these datasets are organized as raw data, preprocessed and MARS-ART reconstruction. The 'RAW DATA' directory contains dicom files representing darkfield images, open beam images and raw projection images. The 'PREPROCESSED' directory contains darkfield corrected, normalized and ring-filtered projection images in tif format. The 'MARS-ART RECONSTRUCTION' directory contains full volume reconstruction in tif format for all the energy bins using algebraic reconstruction technique. Projections are taken for every camera position during the spectral scans and MARS-ART software directly operates on unstitched projections. The geometrical information for every projection image can be accessed from the dicom tags associated with each dicom file.en
