    Abstract

    The latest technology 16-MSCT enables shorter rotation times of less than 500 ms and has therefore a much faster scan time than the previous ones. Although many studies on this topic have been done, evaluation and, more importantly, quantification of this MSCT from signal processing perspective, however, are still lacking. This paper presents quantification of the influence of the most important parameters of MSCT, namely the beam-pitch, reconstruction slice-thickness, and kernels on the 3 D reconstruction and visualisation. The results of our phantom study recommend the use of a beam-pitch of approximately I and a reconstruction slice-thickness of 1.65 mm to obtain optimal 3D reconstructions. Moreover, vessels smaller than 3 mm will be highly affected by any kernel and, therefore, become unreliable. (C) 2003 Published by Elsevier Science B.V.
