An apparatus and method for scanning a set of film images for a patient. A set of film images is assembled for scanning, and a case divider is provided at the beginning or end of the set of film images to serve as an indicator that differentiates the set of film images from any other film images to be scanned. The case divider is disposed on a separate sheet and bears a pattern that indicates its function as a case divider. The set of films is scanned along with the case divider to obtain scanned image data. The case divider pattern is detected in the scanned image data to identify the case divider.
