Résumé

Purpose: Using phantoms, this pilot study aims to outline a method and generate initial data to determine whether the anode heel effect has an impact on image quality and the effective dose. Methods and Materials: A dosimetry phantom and an anthropomorphic adult phantom were positioned with feet towards anode and then cathode and exposed using 75, 80 and 85 kVp; using 18, 22 and 28 mAs. Twelve images were taken and assessed for physical and visual quality by signal to noise ratio and two alternative forced choice (2AFC) with 19 observers.
