A gamma-ray scanner has been used to develop in vivo a rapid, noninvasive technique for the estimation of the mass of successive body scans, and the positions of the centres of those masses. The integrated data are computed to calculate the mass supported by each vertebra and the coordinates of the centre of these masses. These coordinates are transferred from the coordinate system of the gamma ray table to the coordinate system of the X-ray radiographs. In this way, the anatomical relations of the centres of these masses are visualized on the frontal and sagittal full spine radiographs. The method allowed the estimation of various biomechanical parameters such as the height of half the body mass or the compressive load on a specific vertebra. These new parameters were found to be similar to equivalent parameters in the literature. Therefore, these comparisons validate the method. Fourteen normal subjects were tested, and their mean data are proposed as reference.
一种伽马射线扫描仪已被用于在体内开发一种快速、无创的技术，用于估计连续身体扫描的质量以及这些质量中心的位置。对整合后的数据进行计算，以得出每个椎骨所支撑的质量以及这些质量中心的坐标。这些坐标从伽马射线检查台的坐标系转换到X光片的坐标系。通过这种方式，这些质量中心的解剖关系在脊柱正位和矢状位全脊柱X光片上得以显现。该方法能够估计各种生物力学参数，如身体质量一半的高度或特定椎骨上的压缩负荷。发现这些新参数与文献中的等效参数相似。因此，这些比较验证了该方法。对14名正常受试者进行了测试，并提出了他们的平均数据作为参考。
