Abstract: A system for sensing imaging media along a transport path. System includes a light source positioned proximate to a selected location along transport path. A transducer in optical alignment with light source so as to receive light from light source after light crosses transport path provides an output signal having a frequency representative of the presence of imaging media at the selected location.

Abstract: A medical image viewing apparatus and method. In one embodiment, the apparatus is a light box assembly for viewing medical film media. The light box assembly includes an enclosure with a translucent viewing panel, at least two light emitting diodes disposed within the enclosure adapted to illuminate the viewing panel, and a controller controlling the color of the at least one light emitting diode. In a second embodiment, an apparatus is provided for displaying a digital x-ray image. The apparatus includes a display adapted to display the x-ray image and a controller in communication with the display for controlling the color of the displayed x-ray image. The controller includes a continuous color palette by which a color can be selected by a user and the color of the displayed x-ray image is changed responsive to the user's selection of the color.
