A medical system comprises an elongate instrument including a camera configured to capture at least one real-time image of anatomy within a patient anatomy. The medical system further comprises a processor configured to display, on one or more display screens: a three-dimensional patient computer model of the patient anatomy; a synthetic representation of the elongate instrument registered to the three-dimensional patient computer model; over the patient computer model, a representation of a view angle of the elongate instrument, the representation of the view angle being displayed so as to appear to project from a distal tip of the synthetic representation of the elongate instrument; and in a position based on the registration of the synthetic representation of the elongate instrument to the patient computer model, the at least one captured real-time image so as to appear to project from the distal tip of the synthetic representation of the elongate instrument.
