Shielding blocks are frequently used to minimize dose and shield sensitive organs in radiation therapy. The blocks, which are made of high atomic number materials, produce significant dose perturbations in megavoltage photon beams. The effects of these perturbations are studied with special interest in the eye shielding in the treatment of head and neck malignancies. Optimum parameters for the treatment are suggested.
屏蔽块在放射治疗中经常被用于减少剂量并保护敏感器官。这些由高原子序数材料制成的屏蔽块在兆伏级光子束中会产生显著的剂量扰动。在头颈部恶性肿瘤治疗中的眼部屏蔽方面，人们特别关注这些扰动的影响，并提出了治疗的最佳参数。
