| Computed
Topography (CT) Imaging anatomical information
from a cross-sectional plane of the body, each image generated
by a computer synthesis of x-ray transmission data obtained
in many different directions in a given plane. Angiography
uses this method of examining blood vessels
utilizing x-rays and injection of iodine-containing contrast
medium. |
| This
process can visualize blood flow in arterial vessels throughout
the body, from arteries serving the brain to those bringing
blood to the lungs, kidneys, and arms and legs. CT combines
the use of x-rays with computerized analysis of the images.
Beams of x-rays are passed from a rotating device through the
area of interest in the patient's body from several different
angles so as to create cross-sectional images, which then are
assembled by computer into a three-dimensional picture of the
area being studied. |
