Figure 1.

Distributions of current density and field intensity before and after SR-surgery. Panel A shows the position of one array pair on the surface of the patients head, while the craniectomy and underlying regions of interest (tumor, yellow; peritumoral border zone, blue) are shown in panel B. Craniectomy reduced the amount of current shunted through the skin between the arrays (panel C vs E) and redirects the current through the hole in the skull (panel D vs F) and toward the tumor. Panel G shows the change in field intensity induced on the surface of the brain. Craniectomy enhances the field intensity by approximately 300 V/m in the region of interest, while the dose in the surrounding brain tissue remains unaffected.
