摘要： A method and apparatus are provided to filter x-ray beams generated using a CT apparatus or other x-ray based system with displaced acquisition geometry. A CT apparatus may be used having a source (102), a detector (104) transversely displaced from a center (114) of a field of view (118) during acquisition of the projection data, and a filter (146). The filter may absorb at least a portion of overlapping radiation emitted by the source at opposing angular positions. The amount of transverse displacement may be determined for a desired field of view configuration and amount of overlapping radiation. The detector may be adjusted to correspond to the amount of determined transverse displacement. The size and location of the filter may be determined based on the amount of overlapping radiation. The filter may be adjusted to correspond to the determined size and location of the filter.

摘要： An imaging system includes a radiation source (106, T1, T2, T3) that rotates about an examination region and emits radiation that traverses the examination region. The radiation source (106, T1, T2, T3) emits radiation having an energy spectrum that is selectively alternately switched between at least two different energy spectra during an imaging procedure. The system further includes an energy-resolving detector array (116, D1, D2, D3) that detects radiation traversing the examination region. The energy-resolving detector array (116, D1, D2, D3) resolves the detected radiation over at least two different energy ranges and produces energy-resolved output signals as a function of both emission energy spectrum and energy range. The system further includes a reconstructor (126) that performs a spectral reconstruction of the energy-resolved output signals. In another embodiment, the detector array (116) includes a photon-counting detector array (116).
