a Schematic illustration of region of support that was used in scatter correction. b The profiles of the measured detector signal (denoted as “Raw profile”) and the estimated scatter signal (denoted as “Scatter profile”). The profiles were extracted from the central detector column. \({{\varvec{Z}}}_{{\varvec{o}}{\varvec{f}}{\varvec{f}}}\) denotes the stand-off region. \({{\varvec{Z}}}_{{\varvec{t}}{\varvec{o}}{\varvec{p}}}\) and \({{\varvec{Z}}}_{{\varvec{b}}{\varvec{o}}{\varvec{t}}{\varvec{t}}{\varvec{o}}{\varvec{m}}}\) denote the region of support where the measured detector signal was used as scatter fluence
