| ［Abstract］ Objective To explore the relationship between infants’ chest X-ray quality and image density. Methods The image density of high quality X-ray chest films in 90 infants were determined and analyzed.Results In lung field diagnosis area(anterior second and the 4 intercostal space at the mid-clavicular line), the density in neonatal group was(1.05±0.45),that in 2～12 months group was（1.10±0.50）, that in 1～3 years old group was（1.15±0.48）; in right diaphragmatic area the density in neonatal group was（0.42±0.25）, that in 2～12 months group was（0.40±0.27）, that in 1～3 years old group was（0.43±0.28）; in air aeration area the density of neonatal group was（2.00±1.60）, that in 2～12 months was（2.15±1.51）, that in 1～3 years old group was（2.10±1.49）.Conclusion The image density determination of infants’ chest X-ray films may be used as the objective basis of high quality X-ray chest films. |
