case_images: Subdural air volume was 25.11 cm3 (Figure 1), estimated in brain CT according to the following formula: A x B x C / 2.
case_images: 3D reconstruction model of final DBS-lead position and VTA. DBS-lead: deep brain stimulation lead. VTA: volume of tissue activated (indicated in light red).. Figure created by the authors using Lead-DBS (MATLAB)

case_images: Additionally, a volume of tissue activated (VTA) model was constructed based on the stimulation parameters used, corroborating stimulus to the sensorimotor region of the STN, which correlates with the observed motor improvement (Figure 2).
