摘要
γ射线在ＩＣＴ的原始数据中含有各种误差，要作校正．本文研究了能谱硬化与散射修正，并且给出了相应的数学模式。
The various errors in original data of industrial computerized tomography (ICT) must be corrected. This paper investigates the energy spectrum hardening and scattering correction of γ-ray in detail and the corresponding mathematical model is presented.
