    • A medical radiographic device (8) includes a base (10), an elongated supporting structure (15) having multiple sections interconnected by adjustable joints (20, 32, 40), a mount (24, 26, 60) for a radiological camera (28), and a support (48) for a film cartridge. The camera mount (24, 26, 60) includes concave motorized track (26). The film cartridge support (48) is also concave and may also provide motorized film advancement (48). When the camera (28), motorized track (26), and film support (48) are energized, coordinated movement of the camera (28) relative to the film results in a panoramic image of a body part on the exposed film. The device may be a radiologic film scanning device having an elongated housing (110) and a pair of rollers (120) disposed inside. A radiologic film sheet (112) is supported between a first roller (120) and a second roller (120). A radiopaque mask ribbon (130) is disposed around the rollers (120) and the film sheet (112) having an elongated aperture (132) transparent to x-rays passing therethrough. The aperture (132) is perpendicular to the length of ribbon (130). X-rays expose the film sheet (122) through aperture (132) as it moves in the rotating direction of the rollers (120).
