• acquisition
  • Two slices per detector row are acquired, which results in a higher oversampling rate in the z axis, thereby reducing artifacts related to the spiral acquisition and improving spatial resolution down to 0.4 mm 3 . (ahajournals.org)
  • Spiral CT can achieve improved image resolution for a given radiation dose, compared to individual slice acquisition. (wikipedia.org)
  • alternative
  • With spiral CT, thrombus is directly visualized, and both mediastinal and parenchymal structures are evaluated, which may provide important alternative or additional diagnoses. (ahajournals.org)
  • An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of rapidly moving structures, for example the coronary arteries.

  • test
  • In many institutions, spiral CT is becoming established as the first-line imaging test in daily clinical practice. (ahajournals.org)
