Coronary CTA Equipment

  • requires thin detector collimation
    • (detector width of 0.625 or less),
  • thin slice reconstruction (image thickness ≤1.0 mm),
  • multiple simultaneous images (e.g., 64 ormore slices) and
  • cardiac gating (often requiring beta blockers for ideal heart rate).
  • wide-area detectors (ie, 16 cm) that can image the entire heart in one cardiac cycle within a single gantry rotation
