X-ray permeability is one of the important criterions which qualify a material as orthopedic cast. By using a phantom (amputated human lower leg) standardized conditions were created to compare the five customary casts: Cellamin, Lightcase II, Hexcelite, Neofrakt and Baycast. For judging the perceptibility of osseous structures, especially the details of the fracture, the lower and the upper number of clinically used layers were considered. The blank tested valuation showed the well-known advantages of the plastic materials in comparison with plaster of Paris. Within the group of the plastic materials distinct differences were also found.
X射线透过率是衡量一种材料能否作为矫形石膏的重要标准之一。通过使用一个模型（截去的人体小腿）创造了标准化条件，以比较五种常用的石膏：赛拉明、轻护板II型、赫克塞利特、新福雷克和贝卡斯特。为了判断骨质结构的可感知性，尤其是骨折的细节，考虑了临床使用的下层和上层层数。空白测试评估显示了与巴黎石膏相比，塑料材料具有的众所周知的优点。在塑料材料组中也发现了明显差异。
