1. A method of medical procedure image guidance, comprising the steps of: receiving first spatial state data associated with a first medical device; obtaining first medical imaging data associated with the first medical device; receiving real-time second spatial state data associated with a second medical device that is different from the first medical device; obtaining second medical imaging data associated with the second medical device; determining, using one or more processors, a spatial relationship between the first medical device and the second medical device based at least in part on the first spatial state data and the second spatial state data; and causing a display device to display a composite medical image comprising at least a portion of a first medical image corresponding to the first medical imaging data and at least a portion of a second medical image corresponding to the second medical imaging data based at least in part on the determined spatial relationship between the first medical device and the second medical device.
