A newly designed adjustable breast bridge used for patients requiring multiple-plane interstitial breast implants is described. The bridge offers a simple, rapid, and accurate method for determining interplane separation on the sloping breast surface, and is applicable to breasts of all shapes and sizes. The precise interplane spacing of 192Ir sources made possible by using the breast bridge provides uniformity of dose within the implanted volume. The breast bridge allows the radiotherapist to alter interplane spacing to optimise the dose rate to the implanted volume, based upon the preplanned number and strength of 192Ir seeds to be used for each case.
本文描述了一种新设计的可调节乳房桥，用于需要多平面间质乳房植入的患者。该乳房桥提供了一种简单、快速且准确的方法来确定倾斜乳房表面上的平面间间距，适用于各种形状和大小的乳房。使用乳房桥使得192Ir源的精确平面间间距成为可能，从而在植入体积内实现剂量均匀性。乳房桥允许放射治疗师根据每个病例预先计划使用的192Ir种子的数量和强度来改变平面间间距，以优化植入体积的剂量率。
