Based on these data we acquired a series of images on an anthropomorphic phantom with an authentic human temporal bone for each level of iteration the purpose of this was to evaluate them qualitatively. We verified the absence of a reduction in spatial resolution during the use of IRs by measuring MTF 50%. ![]() Methods: Using a Catphan® phantom, we studied the quantitative relationship of the contrast on noise/CDTI vol/IR. The aim of this study is to analyse two IR algorithms (ASiR®, statistical iterative reconstruction and SAFIRE®, model based iterative reconstruction). However, there is no study involving a qualitative and quantitative comparison of the various IRs available for exploring the temporal bone. ![]() Purpose: Iterative reconstruction (IR) has recently demonstrated its ability to reduce the dose of X-rays used in the exploration of several anatomical regions.
