Recon Type

The User CV Recon Type is only available with DWI scans. It is typically used with liver scans. There are two Recon Type states:

  • Set Recon Type = 0 and a zero-filled reconstruction technique is used. It significantly reduces streak (worm-hole) artifacts particularly in images with low SNR and motion. The trade-off for reduced artifact is slightly lower resolution or blurred images in comparison with Homodyne reconstruction.
  • Set Recon Type = 1, the default, and a homodyne reconstruction technique is used. This option produces a sharper image but is more susceptible to worm-hole artifact.
