描述了两种相关方法，用于确定不规则不均匀物体内选定的小体积的电子密度。这些方法的直接医学应用是直接测量骨的矿物质含量。该方法涉及操纵两束伽马射线。测量四种强度，两种透射光束强度和两种散射辐射强度。两种技术之间的区别在于可以使用的伽马射线的能量范围。
Two related methods are described for the determination of the electron density of a small selected volume within an irregular non-uniform object. The immediate medical application for these methods is in the direct measurement of mineral content of bone. The methods involve the manipulation of two beams of gamma -rays. Four intensities are measured, two of transmitted beams and two of scattered radiation. The difference between the two techniques lies in the ranges of energies of gamma -rays that can be used.
