Systems, methods, and computer readable storage media storing instructions for generating an image integrating functional, physiological and anatomical images
Systems, methods and computer-readable storage mediums relate to generating an image that includes functional, anatomical, and physiological images. The generated image may be an integrated image based on the functional image on which the anatomical and physiological images are mapped. The generated image may indicate more than one location of optimal lead placement. The generated image may be useful in pre-planning cardiac intervention procedures.
