A simplified roentgen stereophotogrammetric method is described. It is based on the use of a 50 mm thick reference plate consisting of a carbon-fibre-reinforced polyester box. The patient is placed directly on this box, which makes the methods less cumbersome and more suitable for routine use. The method has been tested in a model experiment designed for detecting small movements between femur and prosthesis at an early stage after total hip replacement. The head and two hemispheres on the prosthesis and three small tantalum balls inserted in the femur serve as reference points. The model experiment now reported shows that the method has acceptable precision.
描述了一种简化的X线立体摄影测量方法。它基于使用一个由碳纤维增强聚酯盒组成的50毫米厚的参考板。患者直接躺在这个盒子上，这使得该方法不那么繁琐，更适合常规使用。该方法已在一个模型实验中进行了测试，该实验旨在检测全髋关节置换术后早期股骨与假体之间的微小运动。假体上的头部和两个半球以及插入股骨中的三个小钽球作为参考点。现在报告的模型实验表明该方法具有可接受的精度。
