We are investigating the characteristics of a prototype digital radiography imaging system in which six two-dimensional diode arrays (CCD) are directly coupled through a bonded matrix (3 x 2) of fiberoptic minifiers to either a scintillating fiberoptic glass plate or to a fluorescent screen. Images are digitally acquired at a rate of up to 30 frames/sec and software corrected for pixel gain, dark current, and geometric distortion. This paper describes the concepts and design configuration of this approach, as well as preliminary results from several phantom and animal studies. Our results indicate that high resolution (> 4 lp/rnm) and high signal-to-noise ratio images can be obtained with this method. However, the complexity associated with this concept cannot be discounted.
