Web29 mrt. 2024 · The usefulness of the advanced modeled iterative reconstruction (ADMIRE) (Siemens Healthineers) MBIR in abdominal CT is reviewed and its noise suppression and/or dose reduction possibilities explored. Quantitative and qualitative methods with phantom and human subjects were used. Webmodel-based IR is the reduction of artifacts [11]. Here, we provide an overview of the lit-erature and describe our experiences with hy - brid IR and model-based IR in pediatric CT. Iterative Reconstruction Techniques IR algorithms reduce image noise, which results in the possibility of lowering CT ra-diation dose without affecting image qual-ity.
