Abstract

A portable dual-mode digital X-ray detector configured to operate in an integrated mode for use in direct digital radiography (DDR) and in non-integrated mode for use in computed radiography (CR). The portable dual-mode X-ray detector comprising a switching mechanism for switching the detector between an integrated mode and a non-integrated mode, a triggering mechanism for use in the non-integrated mode, a communications interface for use in the integrated mode, and at least one memory module for storing image data. The disclosure further includes the methods of operation of the portable dual-mode digital X-ray detector in the integrated mode for use in direct digital radiography (DDR) and in the non-integrated mode for use in computed radiography (CR).
