Abstract	In this study we assess triple-HCB data acquisition for sufficient sampling of the human brain. We find that 2D slices of the brain can be sufficiently sampled by a continuous axially translating triple-HCB source curve prior to their truncation. We hypothesize that if the truncated slices are sufficiently sampled prior to truncation, Tuy's sufficiency condition can be extended to the truncated object. Using simulations we demonstrate that triple-HCB acquisitions with circle-and-line and circle-and-helix scan paths are capable of artifact-free image reconstructions, supporting our hypothesis.
