Abstract
A controller for assisting navigation in an interventional procedure includes a memory that stores instructions and a processor (310) that executes the instructions. When executed by the processor (310), the instructions cause the controller to implement a process that includes obtaining (S410) a three-dimensional model generated prior to an interventional procedure based on segmenting pathways with a plurality of branches in a subject of the interventional procedure. The process also includes determining (S470), during the interventional procedure, whether a current position of a tracked device (250) is outside of the pathways in the three-dimensional model. When the current position of the tracked device (250) is outside of the pathways in the three-dimensional model, the process includes deforming (S480) the three-dimensional model to the current position of the tracked device (250).
