Clinically determined landmarks for a representative patient (Patient 3) with a non-contrast enhancing glioma. The landmarks are displayed in axial, coronal and sagittal projections in T2 (top row), iUS (middle row) and T1 with contrast images (lower row) simultaneously, based on a registration-based fusion (RBF) of the preoperative MR and intraoperatively obtained iUS scans before dura opening. A spatial shift of anatomical structures, e.g. the lateral ventricle, can be observed based on the RBF data
