Image Interpolation

About this task

Image Interpoloation allows the user to control the resolution of the reconstructed images. By default, the system reconstructs images at the next-highest power of 2. For EPI scans, you can change the function so that the system reconstructs the images at their native resolution, defined as the maximum of the acquisition matrix size. This reduces the amount of data and the time to transfer it.
  • When the value of Image Interpolation is 0 (off), images are reconstructed at the native resolution at the maximum of the acquisition matrix size.

    For example, for an acquisition matrix of 90x104, the images are reconstructed at 104x104.

  • When the value of Image Interpolation is 1 (on), images are reconstructed at the nearest power of 2, if the acquisition matrix size is not already a power of 2.

    For example, if the acquisition matrix is 64x64, the image remains at 64x64, but for a matrix of 90x90, the images are reconstructed at 128x128.

Step-by-step instructions

  1. Select the EPI protocol from the GE Protocol Library before you begin the scan.
  2. Go to Scan Parameters > Advanced.
  3. Change the value of CV11 from 1 to 0 to adjust Image Interpolation.
  4. Do the scan.
  5. Export the images for post-processing, as desired.
