摘要： Certain embodiments of the present invention provide systems and methods of improved medical device navigation. Certain embodiments include acquiring a first image of a patient anatomy, a second image of patient anatomy, and creating a registered image based on the first and second images. Certain preferred embodiments teach systems and methods of automated image registration without the use of fiducial markers, headsets, or manual registration. Thus the embodiments teach a simplified method of image registration that allows a medical device to be navigated within a patient anatomy. Furthermore, the embodiments teach navigating a medical device in a patient anatomy with reduced exposure to ionizing radiation. Additionally, the improved systems and methods of image registration provide for improved accuracy of the registered images.
