Spy Glass in Correction Mode

General Information

Use Spy Glass to visually verify the accuracy of the deformation, by moving it to the area of interest on the image slice.

This allows you to view structures in two image sets at the same time (e.g., the shape or size of a tumor).

Color Coded Deformation Grid

When Spy Glass is selected within Cranial Distortion Correction or Spine Curvature Correction, a color-coded deformation grid is displayed by default. Grid lines indicate the direction of correction while colored cells mark the areas of image modification. The color coding is defined by the degree of non-rigid transformation of a particular voxel.

Example Deformation



As displayed in the example above, distortions of DTI images (EPI sequences) are corrected along the A-P direction in the outermost parts of the brain (left image). Spine Curvature Correction results in deformation (compression or extension) of the intervertebral discs (right image).

The red areas indicate the areas of image modification from the original source data. Unshaded areas are not deformed but may have shifted as indicated by the grid lines.
