CORRECTION OF BEAM HARDENING ARTIFACTS IN MICROTOMOGRAPHY FOR SAMPLES IMAGED IN CONTAINERS

摘要

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.
