Area of Science:

  • Cardiovascular Imaging
  • Radiology
  • Medical Visualization

Background:

  • Cardiac computed tomography (CT) scans produce vast datasets exceeding 3,000 images.
  • Traditional axial image interpretation is impractical for these large cardiac CT datasets.

Purpose of the Study:

  • To review and discuss existing and novel visualization techniques for cardiac CT.
  • To highlight the practical application of these methods for interpreting cardiac anatomy.

Main Methods:

  • Multiplanar reformats (MPR)
  • Volume rendering (VR)
  • Maximum intensity projections (MIP)
  • Curved multiplanar reformats (CMPR)
  • "4D" (time-resolved) methods
