Abstract:
1. A multislice CT scanner for imaging a patient comprising: an X-ray source that generates a cone beam of X-rays radiated from a focal spot of the X-ray source wherein the X-ray source is moveable in a rotation plane so as to rotate the focal spot about an axial direction along which the patient is moved to position the patient in a field of view of the scanner; and a detector array comprising a plurality of rows of X-ray detectors that generate signals responsive to X-rays in the cone beam, which signals are used to generate an image of the patient; wherein the cone beam is asymmetric with respect to the rotation plane, and wherein a width of each row of X-ray detectors increases as a declination angle of a line from the focal spot to the row relative to the rotation plane increase and, wherein the width of each row is different.
