Systems, devices, and methods for facilitating the automatic identification, sorting, and positioning of radiographic images. According to one embodiment of the subject invention, phosphorous plates for intra-oral imaging are encoded for automated image set identification, location, and orientation. In certain embodiments, a processing system is able to process encoded identifiers on the phosphorous plates with digitized images depicted on the phosphorous plates to automatically identify, sort, and rotate the digitized images into proper orientations for user viewing.
