While circular cone-beam computed tomography (CBCT) has numerous advantages in CT scanner design, the image reconstruction from circular cone-beam data is known to be approximate since the data sufficiency condition is not fulfilled. This is an unresolved issue yet and may become a problem if the number of detector rows is further increased in the future. The purpose of this work is to evaluate different...
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...
