Abstract
Computed tomography is associated with exposing patients with high radiation doses. This study was conducted to evaluate the effect of reducing the rotation time to reduce the dose without compromising the image quality. Two types of CT scanners were involved in this study: a 4-slice and a 16-slice scanner. A significant reduction in CTD Ivol and DLP were observed with the 4-slice scanner, with a considerably low increase in noise.
