An x-ray system comprises a c-arm base unit, a detector tray and a c-arm movably supported on the base to permit articulation above a patient to be examined. The c-arm has an x-ray emitter emitting x-radiation in an x-ray field, an x-ray detector detecting the x-rays and removably resting at the detector tray. An upper portion of the c-arm holds the x-ray emitter. The c-arm has a retractable lower portion with an articulating assembly removably holding the detector tray at the lower end and articulating the detector tray away from or in towards a center of the c-arm to stowed positions when attached. The c-arm slides with respect to the upper portion of the c- arm such that, when retracted, the upper portion can be placed over the patent who is resting on a surface having an obstruction therebeneath that would prevent the lower portion from accessing under the surface. |
