Imaging Oxygen Pressure in Tissue in Vivo by Phosphorescence Decay

  • Chapter
Oxygen Transport to Tissue XVI

Part of the book series: Advances in Experimental Medicine and Biology ((AEMB,volume 361))

Abstract

A new imaging system, OxyMap®, has been developed to noninvasively obtain two dimensional maps of the distribution of oxygen concentration in living tissue by imaging the decay of the phosphorescent probes, such as Pd-meso-tetra (4-carboxyphenyl) porphine, in the blood. The phosphorescence of these probes is quenched by oxygen according to the relationship:

$$\tfrac{{{T_0}}}{T} = 1 + {K_Q}^*{T_0}^*P{O_2}$$
