1. A method of medical procedure image guidance, comprising the steps of: determining, at a computer system, first real-time, dynamic medical imaging data based on a first spatial state of a first medical device; determining, at the computer system, second real-time, dynamic medical imaging data based on a second spatial state of a second medical device, wherein the second medical device is separate from and distinct from the first medical device; spatially registering the first real-time, dynamic medical imaging data and the second real-time, dynamic medical imaging data; and producing at the computer system, combined dynamic, real-time image guidance data based on the first real-time, dynamic medical imaging data and the second real-time, dynamic medical imaging data; and relative spatial states of the first real-time, dynamic medical imaging data and the second real-time, dynamic medical imaging data.
