Abstract: A method includes performing an x-ray focal spot deflection to generate two complete projections from two different channels of an x-ray detector, wherein the channels are purposefully different from each other in some respect other than being different channels.

Abstract: A CT system includes a rotatable gantry having an opening for receiving a subject to be scanned, a rotatable gantry having an opening for receiving a subject to be scanned, an x-ray source configured to project x-rays having multiple energies toward the subject, and a generator configured to energize the x-ray source to a first voltage and configured to energize the x-ray source to a second voltage, the first voltage distinct from the second voltage. The system further includes a controller configured to cause the generator to energize the x-ray source to the first voltage for a first duration, acquire imaging data for at least one view during at least the first duration, after the first duration, cause the generator to energize the x-ray source to the second voltage for a second duration, and acquire imaging data for two or more views during at least the second duration.

Abstract: Methods and systems for scanning a patient by using a medical imaging device are provided. The methods include determining a defective cell in a row n of a detector of the medical imaging device, determining a mode of operation of the medical imaging device, estimating the output of the defective cell using the determined mode of operation and at least one of a conjugate sample of the defective cell, an adjusted conjugate sample of the defective cell, and an estimate of the output of the defective cell using an output of a corresponding cell in an adjacent row and reconstructing an image of the patient using the estimated value of the defective cell.

Abstract: A CT system is constructed to have diagonally oriented perimeter walls of its detector cells. A CT detector comprised of such detector cells has improved spatial coverage (spatial density) and is better equipped for operation with focal spot deflecting x-ray sources. The number of detector channels is also not increased despite the increase in spatial coverage. Moreover, the detector cells can be constructed without much variance from conventional fabrication techniques.
