Comparison of the computed OER along an SOBP for carbon (black curves) and oxygen (red curves) at different pO₂ levels. The hatched areas represent the clinical interesting regions for hypoxia (0.15% < pO₂ < 0.5%). Doses indicated are prescribed RBE-weighted doses in the target to achieve iso-survival. Plans for using ¹⁶O in the clinics are currently under way at HIT (Heidelberg). Plot from [159], © Institute of Physics and Engineering in Medicine. Reproduced by permission of IOP Publishing.
