Comparison of a clinical high-resolution lung CT scan (a) with a local PBI scan (b) on the same specimen including an artificial lung nodule (detailed view). The clinical scan was acquired with a voxel size of 0.45 mm × 0.45 mm × 0.9 mm (33 mGy air kerma) compared with a voxel size of 0.1 mm × 0.1 mm × 0.1 mm in PBI (4.3 mGy air kerma, one-third of the projection data used for reconstruction). Clearly the lung structures, including interlobular septa (white arrow heads), margins of subsegmental bronchi and pulmonary blood vessels as well as the nodule are depicted in more detail in (b).
