摘要: An X-ray computed tomography apparatus has a beam filter arrangement with regions of different material or/and thickness profile the material. This is disposed in path preceding an examination subject. For multi-spectra hardening correction estimation base lengths, fashioned for implementing projections subject effective arrangement.
