Abstract
A system and method for positioning a device at a desired location in a tubular organ such as an artery. A three-dimensional reconstruction of the organ is obtained, and the desired location is marked in the reconstruction. The device is inserted into the organ and an image is obtained of the device and organ. The reconstruction with the marked location is projected onto a plane from the perspective of the image and the projection and image are superimposed. If the device is not at the desired location, the device is repositioned in the organ and an additional image of the device is obtained. The reconstruction is then projected onto a plane from the perspective of the additional image and the additional image and the projection are superimposed. This process is repeated, as required, until the device is in the desired location.
