A CT imaging system includes a rotatable gantry having an opening to
receive an object to be scanned. A plurality of x-ray emission sources
are attached to the rotatable gantry, each x-ray emission source
configured to emit x-rays in a conebeam toward the object. The CT imaging
system also includes a plurality of x-ray detector arrays attached to the
gantry and positioned to receive x-rays passing through the object. At
least one x-ray detector array of the plurality of x-ray detector arrays
is configured to receive x-rays from more than one x-ray emission source.
