Impact of bowtie filter and object position on the two-dimensional noise power spectrum of a clinical MDCT system
PURPOSE: Noise characteristics of clinical multidetector CT (MDCT) systems can be quantified by the noise power spectrum (NPS). Although the NPS of CT has been extensively studied in the past few decades, the joint impact of the bowtie filter and object position on the NPS has not been systematicall...
