1. A system for navigating to a target through a patient'"'"'s bronchial tree, the system comprising:

  • a bronchoscope configured for insertion into the patient'"'"'s bronchial tree, the bronchoscope defining a working channel;

    a probe insertable into the working channel of the bronchoscope and configured to navigate through the patient'"'"'s bronchial tree, the probe including a sensor, the sensor configured to generate location information and pose information; and

    a workstation in operative communication with the probe and the bronchoscope, the workstation including a memory and at least one processor, the memory storing a navigation plan and a program that, when executed by the processor, causes the workstation to;

    receive the location information and the pose information,execute a maximum intensity projection (MIP) algorithm for a range from a distal tip of the sensor according to the location information and the pose information,present a user interface that guides a user through the navigation plan, the user interface configured to present;

    a three-dimensional (3D) view for displaying a 3D rendering of the patient'"'"'s airways and a display of the navigation plan;

    a local view for assisting the user in navigating the probe through peripheral airways of the patient'"'"'s bronchial tree to the target; and

    an alignment view for assisting the user in aligning a distal tip of the probe with the target, the alignment view including an image generated from the execution of the MIP algorithm.
