Comparison of 2D/3D DIA and μCT

DIA is fast, efficient, and convenient for characterizingCharacterisation thousands of particles quickly; nevertheless, it captures shapes that are fundamentally different than the 3D morphologiesMorphology reconstructed using micro-computed tomographyMicro computed tomography (µCT) (µCT). InTomography DIA particle features are interpreted using external images of a particle. This chapter compared sand particle size and shape descriptors obtained using both DIA and µCTMicro computed tomography (µCT). The accuracyAccuracy of particle volumeVolume assumptions employed for the 2D and 3D DIA methods was also evaluated. Finally, the correlationCorrelation of shape descriptors obtained using 2D, 3D DIA and µCTMicro computed tomography (µCT) were investigated.
