Abstract
Various embodiments of a system for guiding an instrument through a region of a patient are disclosed. The system includes an instrument and a controller that is adapted to receive ultrasound image data from an ultrasound sensor, receive EM tracking data from an EM tracking system, and identify a physiological landmark of the region of the patient based on the ultrasound image data. The controller is further adapted to determine at least one of a position, orientation, or trajectory of the instrument based on the EM tracking data and generate a graphical user interface showing at least one of the position, orientation, or trajectory of the instrument in relation to a plane of the ultrasound image data, and a target zone that is registered with the physiological landmark.
