Map of detectability index.
Top: the detectability index is drawn for all angle pairs (θ, ϕ), with white denoting a high value and black a low value. Bottom: example simulated X-ray images are shown for three selected angle pairs: very good detectability with no overlaps (1), detectability affected by the metal tube (2) and overlaps of the ROI with the massive steel plate yielding very bad detectability (3).
