Abstract
Methods, systems, and computer program products for hierarchical registration () between a blood vessel and tissue surface model () for a subject and a blood vessel and tissue surface image for the subject are disclosed. According to one method, hierarchical registration of a vascular model to a vascular image is provided. According to the method, a vascular model is mapped to a target image using a global rigid transformation to produce a global-rigid-transformed model. Piecewise rigid transformations are applied in a hierarchical manner to each vessel tree in the global-rigid-transformed model to perform a piecewise-rigid-transformed model. Piecewise deformable transformations are applied to branches in the vascular tree in the piecewise-transformed-model to produce a piecewise-deformable-transformed model.
