摘要：
A delivery system and method for radiation shielded brachytherapy comprises a drive assembly, and a plurality of shield assemblies, pivotally mounted to the drive assembly, each having a tubular body defining an outer surface and a bore longitudinally extending between opposite ends of the tubular body. Each of the shield assemblies comprises radiation shielding material extending about a circumferential portion of the tubular body and disposed between the outer surface and the cavity. An interlocking system is operatively mounted to the rotating assembly, and engages a group of the plurality of shield assemblies. The interlocking system is configured for transmitting a rotational input received from a driving mechanism to the group of shield assemblies, for synchronously rotating each shield assembly of the group about their respective longitudinal axis.
