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： Known reconstruction techniques from coherent scattered x-rays apply non-exact reconstruction techniques. According to the present invention, a relatively wide spectrum of wave-vector transfers q of the scattered x-ray photons is acquired. The projection data is interpreted as line integrals in the x y-q space and the projection data is resorted to correspond to an acquisition along any source trajectory. Due to this, an exact helical reconstruction algorithms may be applied and redundant data may be used to obtain a better image quality.
