Abstract

The basic principles of a quantitative tomographic technique for bone mineral determination are considered. The bone mineral content could be evaluated from a single reconstruction using projection data from two different energies. Beam hardening effects and photon counting statistics are studied by computer simulation and found to be the limiting factors in precision and accuracy.

摘要

本文探讨了用于骨矿物质测定的定量断层扫描技术的基本原理。骨矿物质含量可通过使用来自两种不同能量的投影数据进行单次重建来评估。通过计算机模拟研究了束硬化效应和光子计数统计，发现它们是精度和准确性的限制因素。
