摘要：
For fast and exact CT reconstruction, we have conceptualized a triple-source helical cone-beam scanning mode, and formulated a backprojected-filtration (BPF) algorithm for that imaging geometry. The algorithm uses data from the three inter-helix PI-arcs related to the inter-helix PI-lines and the minimum detection windows defined for the triple-source configuration. The proof of the formula is based on Tuy's inversion formula and the geometric relations of inter-helix PI-lines.
