WebFeb 11, 2016 · Background . Images of head CT for the supratentorial compartment are sometimes recommended to be reconstructed with a thickness of 8–10 mm to achieve lesion conspicuity. However, additional images of a thin slice may not be routinely provided for patients with trauma in the emergency room (ER). We investigated the diagnostic … WebFigure 2 illustrates that in one multidetector scanner, the table speed can affect the slice sensitivity profile and effective slice thickness. The top curve was obtained using 4 x 5mm collimation mode, pitch of 0.75 (table speed of 15 mm/rot) and a nominal reconstructed slice thickness of 5mm; the calculated FWHM was 5.31 mm.
