Figure 3

MRI and CT images of a bean root system in a large pot. The same plant grown in a soil filled pot with an I.D. of 81 mm and a height of 300 mm was imaged sequentially with MRI and CT. (a) MRI image shows the roots system in the whole pot with a voxel size of 521 × 521 × 1000 μm3. Root systems of the same plant segmented from CT data (b) on a voxel size of 99 × 99 × 99 μm3. Since the CT dataset was not complete only data of the upper ~75 mm of the pot could be reconstructed and are shown here. The orange colored ring denotes the volume measured also by CT. Arrowheads highlight the same roots in both images. Scale bar: 20 mm.
