We presenteren een experimentele procedure voor het meten van de partiële druk van zuurstof (pO2) in cerebrale vaatstelsel op basis van zuurstof-afhankelijke quenching van fosforescentie. Dier voorbereiding en beeldvormende procedures werden uiteengezet voor zowel grote beeldveld van CCD-gebaseerde beeldvorming van pO2 in ratten en twee-foton excitatie gebaseerde beeldvorming van de pO2 in muizen.
