1. A monitoring device configured to map oxygenation of a tissue containing an injectable, light re-emitting probe, the monitoring device comprising:

  • at least one optical emitter that is configured to excite the injectable, light re-emitting probe;

    at least one optical detector configured to receive the re-emitted light from the probe;

    a signal processor that is configured to resolve the tissue oxygenation at multiple points based on an oxygen-dependent optical response of light emitted by the injectable, light re-emitting probe to generate an oxygen map; and

    a temperature sensor that is configured to detect a temperature of the tissue,wherein the signal processor is configured to receive temperature data from the temperature sensor to calibrate resolving the tissue oxygenation based on the temperature dependence of the oxygen-dependent optical response.
