摘要： An imaging system includes a radiation source (110) that emits radiation that traverses an examination region. A controller (116) activates the radiation source (110) to emit radiation and deactivates the radiation source (110) to stop radiation emission. The controller (116) selectively activates the radiation source (110) to emit radiation at one or more pre-determined angles. In another embodiment, the imaging system includes a data processing component (124) that generates a virtual three dimensional image of an object of interest of the scanned subject based on the image data. In another embodiment, the imaging system is in a communication with a data manipulation and packaging component (128) that generates at least a two dimensional or a three dimensional data set based on the volumetric image data and packages the data set in an object provided to a remote system (132) that manipulates and navigates through the data set.

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.
