A 24-yr-old female patient who was to undergo radiation therapy management for a recurrent low-grade fibrosarcoma on her right knee was found to be 9 weeks pregnant. The patient and her relatives insisted on carrying the pregnancy to maturity, despite undergoing irradiation of her right knee for local control of her disease and to take the teratological risk, if any, that it entails. This paper discusses the measurement of scattered dose in water, fetal dose estimation in an Alderson-Rando human phantom and possible ways of minimizing it.
一名24岁的女性患者，因右膝复发性低度纤维肉瘤需接受放射治疗，却被发现已怀孕9周。尽管为控制病情需对其右膝进行照射，并承担由此带来的致畸风险（如有），但患者及其亲属仍坚持要将妊娠维持至足月。本文讨论了水中散射剂量的测量、在Alderson-Rando人体模型中对胎儿剂量的估计以及将其降至最低的可能方法。
