Abstract:
A CT system includes a rotatable gantry having an opening for receiving an object to be scanned, an x-ray source coupled to the gantry and configured to project x-rays through the opening, a generator configured to energize the x-ray source to a first kVp and to a second kVp to generate the x-rays, and a detector having pixels therein, the detector attached to the gantry and positioned to receive the x-rays. The system includes a computer programmed to acquire a first view dataset and a second view dataset with the x-ray source energized to the first kVp, interpolate the first and second view datasets to generate interpolated pixels in an interpolated view dataset at the first kVp, using at least two pixels from each of the first and second view datasets to generate each interpolated pixel in the interpolated view dataset, and generate an image of the object using the interpolated view dataset.
