The passage suggests that medical tomography operates on the principle that x-rays are superior to sound waves for producing three-dimensional images. sound waves are altered as they pass through regions of varying density. images of the body's interior can be produced by analyzing a single x-ray transmission through the body. the varying densities within the human body allow x-rays to map the internal organs information from x-rays and sound waves can be combined to produce a highly detailed image of the body's interior!
Which of the following is most similar to medical tomography as it is described in the passage? The use of ocean-current meters to determine the direction and velocity of the ocean's mesoscale fields. The use of earthquake shock-wave data collected at several different locations and combined to create a three-dimensional image of the Earth's interior The use of a grid-point sensory system to map global weather patterns. The use of subsurface floats to map large-scale circulation in the ocean The use of computer technology to halt the progress of a particular disease within the human body's internal organs!
