In order to scan an x-ray the scanner must have a transperency adaptor. Many scanners have a small transperancy adaptor designed to scan a single 35mm slide. This is OK for a single x-ray but useless for a panoramic or a full mouth series. The Epsom 4990 listed below has an 8” x 10” adaptor and is priced at about $300. Be warned; some vendors will try and sell you a special x-ray scanner for well over $1,000.
This powerful performer scans multiple slides simultaneously, as well as negatives and photos. And, with its built-in transparency unit, it accommodates film up to 8″ x 10″.
