Reconstruction of the realized target. Realized target reconstruction (AP and ML coordinates of the center) on 2 days post-operative T2 FRFSE axial images. The reconstruction of the ac and pc lines and of the MCL is done on the DV0 plane (left). The ML coordinate is measured parallel to the MCL, while the AP direction is measured perpendicularly to this line on the V2 plane (right) where the target is most visible. The coordinates of the displayed realized target are 2 mm ventral to the ICL, 6.77 mm lateral to the thalamo-ventricular border, and 0.23 mm anterior to the MCL.
