“…As mentioned above, the detector is a linear array detector and the X-ray source has a fan-beam geometry, as shown in Fig. 3 (Léonard et al, 2011). Therefore the 3D structure of the sample bed cannot be obtained by one scan.…”

“…Since then, X-ray tomography has been widely used with drying processes [21, 50, 74, 79-82, 97, 133-136, 141, 144, 145]. Details about the fundamental principles of X-ray tomography can be found elsewhere in the literature [69,91,137].…”

Many changes occur in the structure and properties of a test material during drying as a consequence of moisture evaporation. The use of image acquisition and analysis techniques is proposed here as a potential method of obtaining a better understanding of the different phenomena that can happen during drying. Such techniques can quantify the morphological, textural, and color features of materials and the changes that occur in them. The techniques are convenient to use, accurate, and facilitate rapid measurement. Accordingly, the use of image acquisition and analysis techniques continues to attract considerable research interest in the field of drying. Many such techniques have been applied in this field: scanning electron microscopy (SEM), charge-coupled device (CCD) photography, neutron radiography (NR), magnetic resonance imaging (MRI), X-ray tomography, and so forth. Each technique has its own characteristics and specific applications. SEM is employed to investigate the morphological structure and pore distribution of a sample during drying in the form of magnified 2D images. A computer vision system typically uses two portable CCD cameras to provide 2D top-and side-view images of the sample. These can be used for online monitoring of the change in shape and color and any crack development in the sample during drying. NR and MRI are used for determination of the moisture profiles inside the sample during drying. In addition, MRI can be used to characterize the pore distribution in combination with other technologies. X-ray tomography provides 2D cross sections and 3D tomographic reconstructions of the sample, which can be used to elucidate the volume, crack development, surface area, porosity, and moisture profiles of the sample during drying. Overall, of all these various image acquisition and analysis techniques, X-ray tomography is considered to be the one that has the most promising future in the field of drying.
