Fig. 1From: Hippocampal dosimetry correlates with the change in neurocognitive function after hippocampal sparing during whole brain radiotherapy: a prospective studyAn example of hippocampi contouring was demonstrated in (a) Axial, (b) Coronal and (c) Sagittal views. The bilateral hippocampal structures were contoured in yellow color. The zone for hippocampus avoidance (HA zone) was marked in orange. d Treatment planning was designed and arranged by four arcs in a VMAT plan, in which two full arcs and two non-coplanar partial arcs were employedBack to article page
