研究一种有别于软件校正模型的更为简单实用的射束硬化伪像校正方法。
This paper introduces a simple and practical method to correct the beam hardening artifacts, which is different from the method of software correction model.
传统的射束硬化校正方法，通常需要针对每一种材料测量该材料对射线的吸收曲线。
For the empirical beam hardening correction in computerized tomography (ct), it is necessary to measure an attenuation curve for the material.
实验结果表明，IL校正法能去除射束硬化的影响，并能有效地抑制校正过程中投影噪声的放大。
Experimental results show IL correction method can eliminate beam hardening effect and suppress the projection noise enlargement effectively in correction process.
