Investigate how different anode and filter materials influence image quality and mean glandular dose in screen-film mammography systems using a theoretical computer simulation.
Engineered a computer simulation incorporating every stage of mammographic imaging: X-ray production, filtration, phantom interaction, anti-scatter grid transmission, and screen-film detection.
Calculated image quality index metrics (contrast, spatial resolution, noise) alongside mean glandular dose across multiple anode-filter configurations.
Validated the computational model outputs against physical experimental measurements obtained from mammography equipment.
Observed close agreement between simulation-predicted physical parameters and experimental measurements across standard testing configurations.
Demonstrated that combining a tungsten anode with a rhodium filter reduces glandular radiation dose without causing significant degradation of image quality.
Established the simulation's capacity to evaluate challenging experimental parameters, including alternate material pairings and monoenergetic X-ray beams.
