The size of the field of measurement (FOM) in computed tomography is limited by the size of the x-ray detector. To enlarge the FOM one may laterally shift the detector by up to 50% of its size and apply well-known weighting functions to the rawdata prior to convolution and backprojection. In this case a full scan is required to obtain complete data though there is a small region, the inner FOM, that...
Flat panel detector (FPD) cone-beam computed tomography (CBCT) systems, such as C-arm CT scanners or onboard imaging systems, rotate far slower than a typical motion cycle of the heart or lung. Therefore 4D CBCT is more complicated with flat panel detectors than with clinical CT. Recent approaches for 4D imaging from FPD CBCT either use multiple scans over the same angular range or a single slow rotation,...
