Abstract
A method for obtaining diagnostic information about a region of a living being, the region having a medical device with a radiopaque portion disposed therein. An X-ray beam having a first energy level in excess of the K-absorption edge of the radiopaque portion of the medical device is directed at the region to obtain a first image information and radiographically locate the medical device within the living being and an X-ray beam having second energy level at or below the K-absorption edge is applied to the region to obtain a second image information.
Claims4
A method of implanting a medical device which is expandable in a living body and monitoring flow through the medical device, the method comprising the steps of:
- delivering the medical device on a catheter to a desired location in a living body;
- locating the medical device by imaging the medical device with an X-ray beam having a first energy level in excess of the K-absorption edge of the radiopaque portion of the medical device;
- manipulating the catheter to expand the expandable medical device;
- visualizing flow of a bodily fluid comprising a contrast agent through the medical device by imaging the medical device with an X-ray beam having a second energy layer at or below the K-absorption edge of the medical device.
