Using Automatic Exposure Control in Digital Radiography

computed radiographs of the chest in pediatric patients, Med. Phys. 199:242-252, 1996. Use of a rating system based on degrees of mottle to determine what sensitivity number of a Fuji AC series would be needed to match the mottle in a 600-speed s/f system, then use the actual sensitivity numbers measured to compare CR to s/f.
