1. , a kind of photodynamics tumor imaging method of chemiluminescence probe mediation is characterized in that comprising the steps:

  • (1) will or organize no chemical damage to organism, and the neoplastic lesion position will be had the metabolism specificityPorphyrin class photosensitive reagents 1~

    100 μ

    M be injected into organism or tissue;

    After (2) 10~

    24 hours, will have optionally chemiluminescence probe 1~

    100 μ

    M to singlet oxygenBe injected into organism or tissue;

    (3) be 0.05~

    2.00W/cm with power density 2With wave-length coverage be exciting of 550~

    700nm The even irradiated biological body of light or organize 10~

    80s induces organism or tissue to produce photosensitizationChemiluminescence;

    (4) utilize optical fiber receive module to receive this also from the photosensitization chemiluminescence signal of organism or tissueBe converted into the signal of telecommunication;

    (5) be digital signal with the signal of telecommunication by analog digital conversion;

    (6) processing digital signal and carry out image reconstruction obtains the structural images of organism or tissue.
