Abstract
In this paper, we discuss the requirenients, design approach, and features for a high-performance, laser-based radiographic film digitizer. The scanner is capable of digitizing a radiograph over a 3.5 diffuse density range in 15-30 seconds while not significantly reducing the noise-equivalent-quanta (NEQ) relative to the original analog screen-film image. Three resolutions are possible, corresponding to maximum film sizes of 35 x 43, 24 x 30, and 18 x 24 cm, with pixel sizes of 86, 59, and 43 microns; respectively. Preliminary results of side-by-side comparisons of scanned data reconstructed on pnnted film with the original analog film are discussed, along with future directions for research.
