Image Import Guide with Restore Points for Safe Edits
Importing Images into ITK-SNAP
To import images into ITK-SNAP, follow these steps:
- Open ITK-SNAP and go to ‘File’ > ‘Import’.
- Select the image file format you want to import (e.g., DICOM, NIfTI, or TIFF).
- Choose the location of the image file and select it.
- ITK-SNAP will automatically load the image data and display it in the 3D visualization window.
Using Restore Points for Safe Edits
ITK-SNAP allows you to create restore points, which are snapshots of your image data at specific points in time. This feature enables you to safely edit your images without worrying about losing your original data.
- To create a restore point, go to ‘File’ > ‘Restore Points’ > ‘Create Restore Point’.
- Enter a descriptive name for the restore point and click ‘Create’.
- To revert to a previous restore point, go to ‘File’ > ‘Restore Points’ > ‘Restore’ and select the desired restore point.
