OSEM reconstructed (8 subsets, 10 iterations) disk phantom using simulated single-camera HCB collimation with helical-path acquisition. (a) sagittal slice close to the edge of the phantom and its profile reveal three distorted disks, which where not sufficiently sampled; (b) distorted image of the transaxial slice of the least sampled disk (i.e., the left-most disk in (a)).
