X-ray transparent hospital bed compatible with open geometry portable CT scanners

Abstract

A hospital bed adapted for use with an open geometry imaging system, such as a C-arm imager, is provided. The hospital bed includes a mobile base, a frame, a bed top, and a patient support. At least one portion of the bed top and patient support are substantially radiotransparent. The radiotransparent portions are capable of axial displacement along the lengthwise axis of the bed, thereby allowing the use of an imager on a patient in the bed without interference from the base. The axial displacement is preferably indexed to at least one predetermined stop position. One or more independent lateral sections can be selectively moved away from the radiotransparent portion, allowing for a reduction in the overall width of the bed. A patient transport system is also provided, in which the bed top and attached patient support can be used as a portable support, such as a stretcher, and may be secured to the base for subsequent transport and/or imaging when appropriate.
