Digital projection radiography of the chest.
Direct and film-based radiographic systems are undergoing evaluation by observer performance studies for use in digital imaging of the chest. Many issues intrinsic to digital imaging are not settled, including the minimal pixel size necessary for images of accurate diagnostic quality, the characteristics of the display console, and the usefulness of digital imaging processing techniques. The chest is a particularly difficult anatomic region for examination by digital radiography because of the broad spectrum of disease findings encountered. These issues are discussed in reference to four reports that use observer performance tests for evaluating various facets of chest diagnosis using digital radiography.
