Zusammenfassung:Provided are improved referenceless multi-material beam hardening correction methods, with an emphasis on maintaining data quality for real-world imaging of geologic materials with a view towards automation. A referenceless post reconstruction (RPC) correction technique is provided that applies the corrections in integrated attenuation space. A container-only pre-correction technique also is provided to allow automation of the segmentation process required for beam hardening correction methods. 提供了改进的无参考多种材料射束硬化校正的方法,重点是保持地质材料真实成像的数据质量的同时实现了自动化。提供了种无参考后重建(RPC)校正技术,其在积分衰减空间应用校正。也提供了仅有容器的预校正技术来允许射束硬化校正方法所需要的分割过程的自动化。
