Study Of Image Quality In Digital Radiography

Abstract

The objective of the research was to study the image quality in digital radiography in Modern Medical Center. the data were collected the from radiography department in Modern Medical Center for 40 patient (males and femals) in adult with average age (15-45 ) ,20 patients under went to chest x ray image PA ,10 chest performed by digital radiography (DR) and other 10 chest performed by computed radiography (CR). 20 patients Lumbar spine, 10 spinal cord performed by digital radiography and other 10 performed by computed radiography, this images evaluated by this score (excellent=4 ,very good=3,good=2,acceptable=1) in all each factor images by ten senior graduated students in sudan university and toke the average of images . The percentage of contrast in chest images in DR is 93% and in CR is 91%, the percentage of resolution in chest images in DR is 93.4% and in CR is 90.3%, the percentage of artifact in chest images in DR is 96% and in CR is 93% and the percentage of noise in chest images in DR is 97% and in CR is 94.5% ,the percentage of contrast lumbar spine images in DR is 91.3% and in CR is 87.4%, the percentage of resolution lamer spine images in DR is 93.1% and in CR is 87.7%, the percentage of artifact lumbar spine images in DR is 76.2% and in CR is 72.3% and the percentage of noise lumbar spine images in DR is 97% and in CR is 83.8%. This means the all percentages of images parameters in DR is better than in CR.
