Patent ID: 7016455

Claim:
An imaging tomography apparatus comprising: a first data acquisition system comprising a first radiator and an arcuate first detector for detecting radiation originating from said first radiator; a second data acquisition system comprising a second radiator and an arcuate second detector for detecting radiation originating from said second radiator; a gantry to which said first data acquisition system and said second data acquisition system are mounted for rotation around a common rotation axis; said first detector having a first length measured in an azimuthal direction relative to said common rotation axis, and said second detector having a second length measured in said azimuthal direction, said first length and said second lengths being different; and during rotation around said common rotation axis, said first data acquisition system and said second data acquisition system respectively scanning maximum measurement fields that differ in size from each other, with said first data acquisition system generating a first set of computed tomography projection data, and wherein said second data acquisition system generating a second set of computed tomography projection data.
