The objective of this study is to investigate the ability and limitation of CT scanner for determi-nation of soil structural properties. Some researchers have demonstrated the possibility of using X-ray transmission Computed Tomo-graphic (CT) scanning for determination of bulk density and moisture content in soil analysis. This scanner is an advanced tool in diagnostic radiology used to obtain a nondestructive cross-sectional representation of the human body. To date no experimental technique has been capable of directly and repetitively measuring spatial variation of soil structure. Using a third-generation CT scanner, some experiments related to soil structural analysis have been conducted and the result showed that CT Scanner can be used to determine structural properties of soil. The machine was found to respond in a positive linear fashion to increasing bulk density. The relationship between CT number and moisture content was linear over the range of moisture content evaluated. PETROVIC et al mentioned that CT scanner is a potentially promising tool for research in the areas of compaction, soil management, and cultivation. It was concluded that the CT scanner can be used to determine soil physical condition (soil structure) with good three-dimensional spatial resolution.
