摘要： In predicting failure of an x-ray tube in a computed tomography (CT) system, reference detector elements normally disposed on each end of the detector, receive x-rays directly from the x-ray tube. In accordance with the invention, the output values of the reference detector elements are utilized by a tube condition prediction algorithm to predict a failure in the x-ray tube of the CT system. The tube condition prediction algorithm utilizes at least one model of the CT system and at least one prediction routine, which typically is a Kalman filter, to generate the prediction. The prediction routine uses the model to analyze the output values of the reference detector elements in order to determine the condition of the x-ray tube and predict future performance of the x-ray tube.

摘要： A method and apparatus for use with a volumetric computed tomography (CT) scanning system. In accordance with the present invention, the volumetric CT scanning system utilizes an area detector to acquire projection data. The acquired projection data is stored in memory. The projection data corresponding to groups of pixels of the detector is then rebinned to thereby reduce the amount of projection data that will be utilized in performing an initial volumetric reconstruction of the image. The reconstructed image may then be processed to identify particular regions of interest, such as a pathology. If a particular region of interest is identified, all of the projection data corresponding to the region is then used to retrospectively reconstruct a high resolution image of the region of interest. The retrospectively reconstructed high resolution image can then be processed and analyzed to further evaluate the region of interest.

摘要： A system and method for scanning objects using a non-translational x-ray diffraction (XRD) system is disclosed. The system includes a scanning area through which an object to be scanned traverses and a distributed x-ray source having a plurality of focal spot locations.

摘要： A technique is provided for imaging a field of view using an X-ray source comprising two or more emission points. Each emission point is configured to emit a fan of radiation encompassing less than the entire field of view. The emission points are activated individually and rotate about the field of view, allowing respective streams of radiation to be emitted at various view angles about the field of view. The emission points, which may correspond to different radial regions of the field of view, may be differentially activated to emphasize a region of interest within the field of view. The multiple emission points may be extrapolated along the longitudinal axis in duplicate or offset configurations.
