Abstract
Systems and methods are provided for collecting and processing physical space data for use while performing an image-guided surgical (IGS) procedure. A method includes performing a rigid alignment of a computer model of a non-rigid structure of interest in a patient and surface data in a patient space associated with at least a portion of said non-rigid structure, and computing a deformation of the computer model that provides a non-rigid alignment of said computer model and an organ geometric representation of data, said deformation computed using a set of boundary conditions and field variables defined for said computer model based on said rigid alignment and a parameterization function.
