单词 computed tomography
释义
computed tomography

Electronics and Electrical Engineering
  • An imaging system using X-ray beams that are rotated around, and moved along, a patient’s body to build up a series of cross-section images. The beams are narrow fans that produce a snapshot of the overall reduction in X-ray strength as the beam passes through. Computer algorithms are then used to process the beam data to build the two-dimensional cross-section image. See also electrical impedance tomography.
