GANTRY X-RAY TRANSMISSIVE ELEMENT

摘要

A computed tomography system (100) includes a stationary gantry (104) that houses at least one x-ray source (112) that rotates about an examining region (120) and at least one detector (116) that resides opposite the examining region (120)from the at least one x-ray source (112). The stationary gantry (104) further includes an annular ring (132) disposed about the examination region (120) in a path of the x-ray beam between the at least one x-ray source (112) and the at least one detector (116), wherein the annular ring (132) is substantially opaque to visible light.
