Abstract
Methods and apparatuses for the image guidance and documentation of medical procedures. One embodiment includes combining small field of view images into a recorded image of with a large field of view and aligning the small field of view real time image with the recorded image through correlation of imaging data. A location and orientation determination system may be used to track the imaging system and provide a starting set of image alignment parameters and/or provide change updates to a set of image alignment parameters, which is then further improved through correlating imaging data. The recorded image may be selected according to real time measurement of a cardiac parameter during an image guided cardiac procedure. Image manipulations planned based on the recorded image can be stored and applied to the real time information. The position of the medical device may be determined and recorded through manipulating a cursor in a 3-D image space shown in two non-parallel views.
