A CT (or CAT) scan uses specialized x-ray beams to create highly-detailed pictures of the body. The special x-ray beams pass cross-sectionally through the body and are received by a special detector array, which separates the beam into very thin slices. The high-resolution slices are typically grouped into volumes of data which can be reconstructed into any desired plane without losing resolution (clarity).
