Qualitative Analysis Results of AIDR 3D Image Sets and FBP Image Set in Different-Sized Phantoms

Note.- Values presented indicate mean ± standard deviation. ^*P values indicate result of Friedman test, ^†P₁, P₂, and P₃ indicate result of Wilcoxon test: P₁ indicates difference between FBP and AIDR-mild reconstruction mode; P₂ indicates difference between FBP and AIDR-standard reconstruction mode; and P₃ indicates difference between FBP and AIDR-strong mode, respectively. AIDR = adaptive iterative dose reduction, FBP = filtered back projection, Mild = mild reconstruction algorithm, STD = standard reconstruction algorithm, STR = strong reconstruction algorithm, 3D = three-dimensional
