Influence of reconstruction and kernel: images of test body, hydroxyapatite at a concentration of 200 mg cm−3 using protocol ultralow dose IV and filtered back projection (FBP), adaptive statistical iterative reconstruction (ASIR)-50, ASIR-100 and model-based iterative reconstruction (MBIR) showing corresponding standard (std) kernel on the left and bone kernel on the right. Note the decrease of noise for increased level of iterative reconstruction and std vs bone kernel.
