Graph construction for dual-surface LOGISMOS. (a) Search profiles of a single surface are constructed starting from vessel centerline point μk determined for every IVUS frame. (b) LOGISMOS graph structure of a single surface with arcs enforcing the surface smoothness constraints between adjacent columns on the same frame. (c) LOGISMOS graph structure of a single surface with arcs enforcing the surface smoothness constraints between the corresponding columns on adjacent image frames. (d) LOGISMOS graph structure with arcs enforcing the inter-surface constraints. See [12], [13] for additional details.
