1. A method of illustrating a structure in a subject, comprising: tracking a location of a reference tracking device attached to the structure in the subject as the structure in the subject moves with the reference tracking device attached thereto; determining a plurality of locations of the reference tracking device by tracking the reference tracking device over a period of time at selected time points; acquiring a plurality of frames of images of the structure in the subject over the period of time and at least at the selected time points while tracking the reference tracking device over the period of time at the selected time points; correlating each of the acquired plurality of frames of images to a tracked location of the reference tracking device at the selected time points; and generating a correlated image data set based on the correlated each frame of the plurality of frames of images to the tracked location of the reference tracking device.
