The effects of iterative reconstruction and kernel selection on quantitative computed tomography measures of lung density

PURPOSE: To determine the effects of iterative reconstruction (IR) and high‐frequency kernels on quantitative computed tomography (qCT) density measures at reduced X‐ray dose. MATERIALS AND METHODS: The COPDGene 2 Phantom (CTP 698, The Phantom Laboratory, Salem, NY) with four embedded lung mimicking...
