本研究比较了新型妊娠模型体模与手工体模的形状和辐射测量点，以确定哪种模型更适合在X射线检查期间测量胎儿辐射剂量。新型妊娠模型体模的构建使用拟人体模结合两个不同尺寸的定制腹部体模模拟妊娠，这是由聚氨酯树脂制成的。聚氨酯树脂的尺寸和形状是根据从一家医院的18名孕妇的计算机断层扫描检查中收集的腹部尺寸和形状设计的。手工制作的妊娠模型体模使用拟人体模和一个装有水的海滩球构建。与手工体模相比，新型妊娠模型体模上增加了剂量测量点。我们的模型体模在形状和辐射测量点方面对手工体模进行了改进。我们首次制作了模拟实际患者形状和大小的妊娠模型体模。
This study presents a comparison of novel pregnant model phantoms with a handmade phantom in terms of shape and radiation measurement points to determine which model is more suitable for measuring the foetal radiation dose during x-ray examinations. Novel pregnant model phantoms were constructed using an anthropomorphic phantom in combination with two differently-sized custom-made abdomen phantoms simulating pregnancy, which were constructed from a polyurethane resin. The size and shape of the polyurethane resin were designed based on abdominal sizes and shapes collected from the computed tomography examinations at 18 pregnant patients of one hospital. The handmade pregnant model phantom was constructed using an anthropomorphic phantom and a beach ball containing water. Compared with the handmade phantom, there were additional dose measurement points on the novel pregnant model phantoms. Our model phantoms improved upon the handmade phantom in terms of shape and radiation measurement points. We produced pregnant model phantoms that simulated the shapes and sizes of actual patients for the first time.
