Noise power spectrum (NPS) results measured by a uniform phantom. ac Each line represents the standard 50% adaptive statistical iterative reconstruction-V (50% ASIR-V, blue line), 100% ASIR-V (blue dotted line), medium-strength deep learning image reconstruction (DLR-M, red line), and high-strength deep learning image reconstruction (DLR-H, red dotted lines) at the dose level of a 1 mGy, b 3 mGy, and c 5 mGy. The NPS peaks of all reconstitution methods decreased in the order of 50% ASIR-V, DLR-M, 100% ASIR-V, and DLR-H
