Abstract:
1. A system for imaging a body to guide a medical operation, the system comprising: a transducer to scan an anatomy; a signal processing unit coupled to the transducer to generate a plurality of first images of the anatomy including a heart, each of the first images corresponding to a particular position and orientation of the transducer relative to the anatomy; means for combining the plurality of first images of the anatomy into a recorded image of the anatomy, the recorded image having a field of view of the anatomy larger than each of the plurality of first images; means for obtaining a real time image of the anatomy during the medical operation, the real time image having a field of view of the anatomy smaller than the recorded image, the real time image containing an image of a medical device used in the medical operation in a portion of the anatomy; means for receiving real time measurements of a cardiac parameter; means for determining a cardiac phase in which the real time image corresponds to based on the real time measurements of a cardiac parameter; means for selecting the recorded image based on the cardiac phase from a plurality recorded images that are associated with different cardiac phase of the heart, before aligning the real time image with the recorded image; and means for aligning the real time image with the recorded image through correlation of imaging data from the real time image and the recorded image to determine a spatial relation between the real time image and the recorded image.
