Maximum difference (%) between rods with and without K₂HPO₄ concentration as a function of Gaussian filter size in the CTAC maps. Maximum difference (%) between rods with and without K₂HPO₄ concentration as a function of Gaussian filter size in the CTAC maps. The maximum difference was observed in the rods with K₂HPO₄ concentrations of 960 mg/cm³ when the Gaussian filter size was 0–16 mm and 26–30 mm. The maximum differences when Gaussian filter sizes of 18 mm and 20–24 mm were observed in the rods with 666 mg/cm³ and 275 mg/cm³, respectively
