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