  • Rotary energy shield for computed tomography scanner
    Patent number: 5937028
    Abstract: In a computed tomography (CT) scanner, an X-ray shield is mountable to a gantry for absorbing randomly scattered X-ray radiation. The shield is rotatable with the gantry disk for regulating the emission of X-ray radiation near its source. The shield is preferably lined with an energy-absorbent material to provide safe energy levels in the environment external to the system. By minimizing the surface area of the shield, the present system results in significant weight reduction and ease of installation over prior shielding systems.
