Abstract: An x-ray imaging apparatus revolves a digital radiation detector and a radiation source about an imaging area where a subject is positioned to be imaged. A housing encloses the source and the detector, and includes an open housing gap to allow movement of the subject into the imaging area by moving through the open gap. A housing extension may be deployed to close the housing gap and to enclose the detector as it revolves. Shielding assemblies prevent exterior access into the housing.

Abstract: A method for managing a portable x-ray detector for an x-ray imaging apparatus registers at least one portable detector with a processor that is associated with the x-ray imaging apparatus. A generated signal is indicative of the location of the registered portable x-ray detector relative to the x-ray imaging apparatus. An alert indication is provided when the generated signal indicates separation of the registered portable x-ray detector from the x-ray imaging apparatus beyond a predetermined distance.
