• Mechanical condition
• Collimation assessment
• Evaluation of focal spot performance
• Evaluation of automatic exposure control system performance
• Uniformity of screen speed
• Artifact evaluation
• Phantom image quality evaluation
• kVp Accuracy and reproducibility
• Half-value-Layer measurements
• Breast Entrance Exposure, Average Galndular Dose and Radiation Output
• Viewbox Luminance and Room Illuminance
• CNR and SNR evaluation-digital system
• Review workstation evaluation-digital system
• Hardcopy display evaluation-digital system
