Abstract

The image quality of a special high-resolution computed radiography (CR) imaging plate is compared with that of conventional screen-film radiography via measurements of physical factors related to the signal and noise of each detector system. Physical parameters reflecting image contrast, spatial resolution and signal-to-noise characteristics are measured as a function of radiation dose for each detector configuration. Standard signal detector configurations for the acquisition of plain film and CR images are compared with those from a modified film cassette containing both a CR plate and conventional screen-film for a dual-image recording technique. The modified dual detector film cassette configuration allows for a single-exposure, simultaneous acquisition of images for the direct clinical comparison of conventional screen- film and CR radiographs. The small physical size of the newborn chest and the types of lung processes that must be evaluated in the critical care neonate present a particular challenge to the spatial resolution limitations of CR. The clinical utility of the special high-resolution CR plate is assessed for such neonatal intensive care unit applications.
