摘要：
Methods and apparatuses for guiding the positioning of a device with a position tracking sensor and pre-recorded images. At least one embodiment of the present invention uses pre-recorded time-dependent images (e.g., anatomical images or diagnostic images) to guide the positioning of a medical instrument (e.g., catheter tips) using real time position tracking during diagnostic and/or therapeutic operations with pre-recorded images. In one embodiment of the present invention, predetermined spatial relations are used to determine the position of a tracked medical instrument relative to the pre-recorded images.
