CT scans of an artificial heart valve (white) in place in the heart, seen from the top (left) and side (right). This is a mechanical double tilting disc valve, which has been implanted as a replacement for a damaged mitral valve. Heart valves preent the flow of blood in the wrong direction in the heart. The replacement valves ensure correct blood flow. CT scanning uses numerous X-rays taken from different angles to build up 2-D slice images through an organ. | |
