<p>An optical scanner assembly for exposing an image on a piece of photosensitive film (66) positioned within an internal drum type exposure assembly (54). The optical scanner assembly is part of a laser imaging system (30) suitable for use in a medical imaging system. The optical scanner assembly includes a laser mechanism (76) for producing a laser beam (88) representative of the image to be exposed on the photosensitive film (66). A first lens system (78) is provided for shaping and focusing the laser beam in a first direction, including a long, flexible cylinder lens (L3). A second lens system (80) is provided for shaping and focusing the laser beam in a second direction, including a second cylinder lens (L2) oriented generally perpendicular to the long, flexible cylinder lens (L3). A scanning and directing system is provided for directing the laser beam (88) and scanning the laser beam (88) across the photosensitive film (66) in an image-wise pattern, including a rotating scanner mechanism (136), wherein the long, flexible cylinder lens (L3) is located between the rotating scanner mechanism (136) and the photosensitive film (66).</p> |
