Figure 2

MRI and CT images of a bean root system in a medium soil filled pot. The same plant grown in a soil filled pot with an I.D. of 56 mm and a height of 200 mm was imaged sequentially by MRI and CT. (a) MRI image measured with a voxel size 375 × 375 × 1000 μm3. The CT image (b) shows the root system measured of the same plant segmented on a voxel size of 68 × 68 × 68 μm3. Roots in the lowest part of the pot could not be segmented and are therefore not shown. (c) CT-MRI co-registration: the CT image is in red and the MRI image in grey. Arrowheads highlight roots visible in CT but not in MRI. Box highlights area where few roots are visible in CT. Scale bar: 10 mm.
