How to prepare your T1-MRI
1. Check the MRI orientation
- Make sure that all the MRI views (axial, coronal, sagittal) correspond with their titles, and that the L/R (left/right) and A/P (anterior/posterior) markers are correctly placed.
- If you have to fix the MRI volume, right-click on the MRI Viewer > Figure > Edit volume. Then:
- Click as many times as needed on any "ZXY" button (permutation of dimensions).
- Use the rotate and flip buttons to align all the views according to the L/R and A/P indicators.
2. Check left / right
- Make sure that the left part of the axial image is really
the left hemisphere.
3. Select the SCS and MNI fiducials
- To select a fiducial: move the cross to the point you want
to select, and then click on the "Set" button of the fiducial you want
to define
- Contrast adjustment: right-click and move mouse up/down.
