Figure 7From: MR-guided focused ultrasound technique in functional neurosurgery: targeting accuracyLesion volumes. Volumes of the first 27 lesions with mean and standard deviation (Std Dev) using two different methods. (A) Volumes reconstructed from surface measurements on 3D T1-weighted post-operative scans. (B) Calculated volumes with the three-dimensional ellipsoid approximation. (C) Differences between the ellipsoidal approximations and the reconstructed volumes in percent.Back to article page
