    摘要: The present disclosure relates to the performing spectral calibration of a CT imaging system. In accordance with certain embodiments, spectral calibration phantoms are scanned while positioned on a table in the imaging volume of the CT imaging system. The scans of the calibration phantoms, in conjunction with air sans performed on the CT imaging system, are used to derive information about the deviation of the measured phantom scans from an ideal. The deviation information is in turn used to derive spectral calibration vectors that may be used with the CT imaging system.

    摘要: A method of imaging comprises performing a scout image of an object and aligning major regions of interest within the object by comparing the scout image with a pre-determined atlas image. In a further embodiment, a method of imaging using a computed tomography (CT) scanner is provided and comprises performing a scout image of a subject and aligning major anatomical regions of interest within the subject by comparing the scout image with a pre-determined atlas image. Further, an imaging system for us with a computed tomography (CT) imaging device is provided and comprises a processor configured to perform aligning major anatomical regions of interest within a subject by comparing a scout image with a pre-determined atlas image, and wherein the major anatomical regions are used for automated localization for Scan Range and/or Exam split.
