1. A method, comprising: registering a first coordinate system of a fluoroscopic imaging system and a second coordinate system of a magnetic position tracking system; computing a three-dimensional (3D) map of an organ of a patient using the magnetic position tracking system; using the registered first and second coordinate systems, calculating a field-of-view (FOV) of the fluoroscopic imaging system in the second coordinate system; creating from the 3D map a two-dimensional (2D) image that simulates a fluoroscopic image that would be generated by the fluoroscopic imaging system if radiation was applied to a subject by the fluoroscopic imaging system at the calculated FOV; and displaying the 2D image that simulates the fluoroscopic image.
