Abstract
A method of ascertaining imaging quality in a computed radiography (CR) system includes providing a substrate having fluorescent test pattern disposed thereon. The substrate is disposed in place of the standard storage-phosphor screen and scanned as if reading out a storage screen. The detected signals form a read-out image which is then compared against the test pattern to judge image quality.
