Performance of x-ray generators and unnecessary dose in mammography.
All x-ray equipment used for mammography in Finland was studied and performance assessed. Numerous functional differences and malfunctions were found in the generators. Medically unproductive absorbed skin dose varied from 0.15 to 130 mrad (1.5-1,300 microGy) per exposure for an average breast. Corrective actions are recommended.
