Archaeology has changed, focusing less on treasure and more on the details of life and the mysteries of death, using sophisticated tools including medical technology. In 1968, an anatomy professor X-rayed the mummy and revealed that its breastbone and front ribs were missing. Today, computed tomography (CT) assembles hundreds of cross-sectional X-rays, like slices of bread, to create a three-dimensional virtual body. According to the passage, a CT scan improves on an ordinary X-ray because it:
Acombines many cross-sectional images into a three-dimensional body
Bis far cheaper to perform
Crequires opening the mummy
Duses no radiation at all
Answer & Solution
Correct answer: A. combines many cross-sectional images into a three-dimensional body
CT stacks hundreds of cross-sectional X-rays into a 3-D virtual body, unlike a flat X-ray.
