    Comparisons of quantitative pulmonary measurements using different tube current and reconstruction settings (n=22)
    Figure Legend Snippet: Comparisons of quantitative pulmonary measurements using different tube current and reconstruction settings (n=22)

    Techniques Used:

    Example of emphysema measurements made by the workstation used in this study. Notes: Low attenuation areas (LAA, < −950 HU) are shown as red-colored areas. For this case (81 year old male, 62 kg), when using AIDR3D, measured LAA% results were 6.8% at 240 mA, 7.7% at 120 mA, and 8.0% at 60 mA. When not using AIDR3D (ie, when using FBP), LAA% results were 9.2% at 240 mA, 12.0% at 120 mA, and 15.3% at 60 mA. Note that LAA% measurements were obtained automatically for the entire lung and not from these single axial images. Abbreviations: LAA%, percent low attenuation area; AIDR3D, Adaptive Iterative Dose Reduction using Three Dimensional Processing; FBP, filtered-back projection; HU, Hounsfield unit.

    Techniques Used:

    Image noise analysis. Notes: At each tube current, greater image noise was observed on scans with filtered-back projection (FBP; without AIDR3D) than on those with AIDR3D. An FBP scan at 60 mA showed the greatest image noise. Note that each AIDR3D and FBP pair at three tube current settings was reconstructed from a single set of raw data. Abbreviations: AIDR3D, Adaptive Iterative Dose Reduction using Three Dimensional Processing; SD, standard deviation; HU, Hounsfield unit.

    Article Title: Evaluation of four computed tomography reconstruction algorithms using a coronary artery phantom

    doi: 10.21037/qims-23-1204

    Figure Lengend Snippet: Peak CT number and CNR at different stenoses and reconstruction algorithms

    Article Snippet: The images were reconstructed using the following four reconstructions: hybrid iterative reconstruction (HIR) (AIDR3De Standard; Canon Medical Systems), MBIR (FIRST Cardiac Standard; Canon Medical Systems), DLR (AiCE Cardiac Standard; Canon Medical Systems), and 2nd generation DLR (PIQE Cardiac Standard; Canon Medical Systems).

    Techniques: Standard Deviation

    Comparison of the peak CT number in each reconstruction method. In the case of 25% stenosis, significant differences are found between 2nd generation DLR and MBIR, DLR and MBIR, as well as DLR and HIR. However, for 50% and 75% stenosis, no statistically significant differences are found among the different reconstruction methods. ****, P<0.001.
