Increase in brain tissue oxygen availability induced by localized microwave hyperthermia.
The present experiments demonstrate by direct measurements, that localized hyperthermia produced by microwave irradiation increases the oxygen levels in brain tissue in a manner dependent on tissue temperature, with concomitant breaking of the oxygen autoregulation, thus allowing for an additional increase in TpO2 upon O2 breathing.
