Wireless x-ray detectors have come into vogue and are now available from a half dozen vendors. They are being offered singly, as a digital upgrade for analog x-ray systems, for example, or as the core of portable and advanced fixed radiography systems.

This potential problem stems from the success of digital radiography.
