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.
该方法对X射线进行一定程度的预硬化，通过实验获得预硬化材料种类及射束硬化伪像的校正规律。
The method made the X-ray beam harden at first, and then the kinds of prehardening materials and correction rule of beam hardening artifacts were obtained through experiment.
若直接用多色投影数据来重建图像，就会出现射束硬化伪迹，这种硬化伪迹如果不校正就会影响医学诊断和工业检测的结果。
Once this kind of data is used to reconstruct the image directly, beam-hardening artifacts appear in the reconstructed image.
