Abstract
Medical imaging systems and methods are provided herein that provide for navigation and procedure planning without segmentation. A method comprises receiving, by a medical imaging system having at least one processing device, three-dimensional image data of a patient anatomy. The method also comprises filtering the three-dimensional data to display a portion of the three-dimensional image data that is associated with the patient anatomy and receiving, at the processing device, input from an operator input device. The input comprises navigational directions for virtual movement within a space defined by the three-dimensional image data. The method also includes tracking the virtual movement, defining a tracked pathway based on the tracked virtual movement, and generating a model of the patient anatomy based on the tracked pathway. The model of the patient anatomy is a line model including one or more lines based on the tracked pathway.
