Abstract: In order to solve the technical problem of root imaging in larger-scale soil sample, a 160kV minifocus X-ray Cone-beam Computed Tomography (CBCT) was used in this paper to do a test for root imaging in six soil samples with the diameters of 210 mm and 120 mm. It is shown in the result that Using the CBCT system available is possible to implement plant root imaging in larger soil samples with over 200 mm diameter by the means of increasing tube voltage and current, effective filtering, system correction, artifact correction, corresponding parameter setting and improving reconstruction, and then the imaging quality of samples’ slices is better while soil particle is smaller.
