    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: A method is provided for imaging a portion of a patient that moves as a patient breathes. A motion map is produced of the portion's motion during a breathing cycle of the patient. A scanning protocol is generated using information obtained from the motion map for a given source/detector position and a given point in the breathing cycle. The scanning protocol comprises at least one setting for at least one imaging apparatus component such that a desired amount of x-ray dosage is applied to the portion of the patient at the given source/detector position and the given point in the breathing cycle. An imaging scan is performed of the portion of the patient. The at least one imaging apparatus component is adjusted during the imaging scan.

    摘要: The present invention relates to an imaging apparatus for generating an image of a region of interest. The imaging apparatus comprises a radiation source (2), a detection unit (6) for generating detection data and a moving unit (1, 7, 8) for moving the radiation source (2) and the region of interest relative to each other, while the detection data are generated. The imaging apparatus further comprises an identification unit (13) for identifying in the detection data high density detection data and non-high density detection data. A density weighting unit (14) density weights the detection data, wherein at least a part of the high density detection data has a smaller density weight than the non-high density detection data, and a reconstruction unit (15) reconstructs an image of the region of interest from the weighted detection data.
