computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body. These slices are called tomographic images and contain more detailed information than conventional x-rays. Once a number of successive slices are collected by the machine’s computer, they can be digitally “stacked” together to form a three-dimensional image of the patient that allows for easier identification and location of basic structures as well as possible tumors or abnormalities.
The GOES system of satellites, which tracks weather and other things, is in a geosynchronous orbit, 36,000 kilometers (22,000 miles) above the earth. These satellites travel at about 11,000 kilometers per hour (7,000 miles per hour).
