Computed tomography was used to find a sensitive parameter for bone mineralization. A precision scanning instrument was constructed for determination of the mineral distribution in sections of the forearm. The quality of the reconstructed images allows separate quantification of compact and spongy bone even when gamma rays are used. Computer simulation and measured of models and macerated human bones showed that under clinical conditions it is possible to quantify spongy bone density within an accuracy of +/-2%.
计算机断层扫描被用于寻找骨矿化的敏感参数。构建了一台精密扫描仪器,用于测定前臂切片中的矿物质分布。即使使用伽马射线,重建图像的质量也能实现对密质骨和松质骨的单独定量。计算机模拟以及对模型和浸软的人体骨骼的测量表明,在临床条件下,可以在±2%的精度范围内对松质骨密度进行定量。
