We have undertaken a computer study that explores the conditions under which seed ribbons may replace iridium 192 wires in the Paris System. Compared with continuous iridium 192 wires, seed ribbons demonstrate greater inhomogeneity and loss of flexibility, simplicity, and other advantages. Nonetheless, we have defined the conditions where seed ribbons may be used in the Paris System to give satisfactory dose distributions and acceptable levels of heterogeneity within any given implant volume. These conditions include seed length, spacing between seeds, number of seeds per ribbon, and geometric arrangement of ribbons.
我们进行了一项计算机研究，探讨在巴黎系统中种子带可替代铱192线的条件。与连续的铱192线相比，种子带表现出更大的不均匀性，并且在柔韧性、简易性等方面有所欠缺。尽管如此，我们已经确定了在巴黎系统中使用种子带的条件，以便在任何给定的植入体积内给出令人满意的剂量分布和可接受的不均匀性水平。这些条件包括种子长度、种子间距、每条带上的种子数量以及带的几何排列。
