三维适形放射治疗（3DCRT）和调强放射治疗（IMRT）计划显示出与靶体积高度适形的辐射剂量分布。这些放射治疗模式的成功临床实施需要精确定位靶点，以避免地理失误。通过正确使用固定装置，可以有效地减少目标位置的不准确性。本文综述了一些固定装置，已被使用和/或有潜力被用于调强放射治疗。综述的固定装置包括立体定向支架、Talon系统、热塑性模具、Alpha Cradles和Vac-Lok系统。这些设备在不同的解剖部位的实施进行了讨论。
Three-dimensional conformal radiation therapy (3DCRT) and intensity-modulated radiation therapy (IMRT) plans show radiation dose distribution that is highly conformal to the target volume. The successful clinical implementation of these radiotherapy modalities requires precise positioning of the target to avoid a geographical miss. Effective reduction in target positional inaccuracies can be achieved with the proper use of immobilization devices. This paper reviews some of the immobilization devices that have been used and/or have the potential of being used for IMRT. The immobilization devices being reviewed include stereotactic frame, Talon system, thermoplastic molds, Alpha Cradles, and Vac-Lok system. The implementation of these devices at various anatomical sites is discussed.
